221B Baker Street, London

More than ten months have passed since the world's only consulting detective committed suicide by jumping off a building, and his roommate, former military doctor, John Watson, could not stand his death and moved out of 221B Baker Street, and the landlord, Mrs. Hudson, was reluctant to rent out the room upstairs.

The upstairs was so unused that the whole of 221B was particularly deserted because of the absence of the previous tenant. Mrs. Hudson had wanted to go up and see it today, but she didn't go upstairs, she was really afraid of touching the scene, and she didn't find it interesting to watch the soap opera at night. As she was about to turn off the television and go to bed, she heard movement outside the door and someone opening the door, and Mrs. Hudson was startled, picked up the frying pan and waited carefully for the door to open.

Erin pushed the door open and looked at Mrs. Hudson as she held the frying pan.

Mrs. Hudson put down the frying pan and said angrily, "Why are you here?" "I think that Erin was chosen as a partner by a brain-opening consulting criminal, and she and Sherlock took the bait and staged a fake breakup. Mrs. Hudson didn't know the inside story, so she knew that the two of them had broken up, and she didn't see Erin show up when Sherlock had an accident, but she didn't expect Erin to come back to Baker Street, and the old lady was still angry in her heart, for Sherlock.

Erin took two steps inside, but she didn't speak.

Mrs. Hudson noticed the ring on her ring finger and asked, "Are you married?" ”

Erin corrected, "Engaged." ”

Mrs. Hudson's heart was twisted, and her tone was a little rushed: "You really look forward-" The following words swallowed back when she saw the little Zhengtai walking in from behind Erin, and then looked at the appearance of the little Zhengtai, and then looked at the calm Erin, and her heart was even more twisted. I thought she might have misunderstood Irene, I think this little boy should have been adopted by Irene, he looks much like Sherlock, and if Erin had no relationship with Sherlock, she would never do this. Mrs. Hudson sighed, and when she spoke again, her tone changed to worry: "Your fiancé doesn't mind, does he?" ”

Sherlock: "......"

Erin blinked, she looked down at her fiancé, who had become a four-year-old fiancé, and said tentatively, "You said Sherlock—"

"This kid's name is Sherlock, too? Did you name him? Mrs. Hudson gave Sherlock a loving look, "Oh, he's so cute, so your fiancé wouldn't mind you adopting one, would he?" ”

"Mrs. Hudson!" Sherlock couldn't help but call the brainless landlady, and he was about to say something more, such as revealing his identity, when he was stunned to find that Mrs. Hudson's eyes were red, inexplicably, and he swallowed the rest of the words. He reached out and grabbed Erin's fingers, tilted his head and stopped talking.

Erin sighed inwardly, and without explaining anything to Sherlock, she asked Mrs. Hudson if she could rent out 221B again.

Mrs. Hudson said with a hint of resistance, "And then move in with your fiancé?" ”

Erin: "...... With Sherlock. ”

"Oh, oh, that's good." Mrs. Hudson looked at the little boy with pity, and the other little Sherlock took them upstairs, and as she went upstairs, she murmured, "Since Sherlock...... After that incident, John also moved out, and I couldn't bear to rent out the house. ”

Sherlock had actually deduced John downstairs that John had moved out, and now that he had heard Mrs. Hudson say so, he couldn't help but flatten his mouth, not too happy. In fact, from the time they flew from Tianchao to London, he exuded an air of "I'm not happy", probably related to the fact that everyone praised him for his cuteness along the way, that Miss Shikong took special care of him on the plane and brought him a glass of milk, and that someone asked Erin if he was her child, and so on.

Erin lowered her eyes and asked with a fake look, "Do you want me to carry you away, Xiali?" ”

Sherlock: "...... No, no, no. ”

Getting smaller is so unhuman rights, no, he is still living by Eric as always.

The furnishings in the house were the same as before Sherlock left, but they hadn't been cleaned for a long time and were covered with dust. Mrs. Hudson explained, "Sherlock has never liked me to clean," she coughed twice, looked over and asked, "Your fiancé, what's his name?" When are you going to get married? ”

Mrs. Hudson sighed, "Sherlock hadn't been gone long before you looked ahead. Uh, I mean you really look ahead, where did you adopt this cute little guy? Seriously, he and Sherlock looked so much like each other when they were kids, and I've seen pictures of his mommy bringing them...... Have you ever wanted to go over and get a paternity test? After Sherlock came to rent a room with me, I didn't see him have any other girlfriends except for you, but who knows. ”

Sherlock: "......"

Erin: "...... Mrs. Hudson, your kettle is open. ”

"Really?" Mrs. Hudson said this but went downstairs, and when the old lady left, Erin muttered for a moment and said, "Speaking of which, when you, I mean you come back as an adult, you will need to explain to Mrs. Hudson where the little boy suspected of being your illegitimate child has gone." ”

"Boring!" Sherlock snorted, pouting and hanging a soy sauce bottle. He looked around and stood still. Erin listened to the action downstairs, "Mrs. Hudson is making tea, and if she says something that leaves us speechless, I think we'll come back another day, what do you think?" ”

"Good idea." Sherlock immediately agreed, and the two of them quickly went downstairs, saying goodbye to Mrs. Hudson before she came out with the tea tray. When they got out of the door of 221B Baker Street, they saw a small black car slowly approaching.

Erin glanced at the black car that stopped, and then looked down at Sherlock, Sherlock is really easy to blow up now, so he will blow up: "What? ”

Erin asked in a long tone, "Do you miss it?" ”

"What are you talking about, Irene?" Four-year-old Sherlock was really unconvincing when he said that, but rather "a young man" - at least that's how he looks like it now - is cute. As soon as Erin turned her head and snickered, Sherlock saw through her, "Shut up! ”

Erin suddenly had a flash of inspiration and was about to talk to Sherlock, but as soon as she said "I-" Sherlock said angrily, "I told you to shut up." ”

"Are you sure? Because something suddenly occurred to me. Imagine what would happen if you drank an anti-aging agent on top of what you had done? After Erin finished speaking, Sherlock, who had never lacked the courage to try, was a little eager to try, but before that, they still had to get in the little black car to meet the younger brother who had waited for his brother to return to London since they had finished their "trip" to Serbia, and as a result, he had waited for a month, and if it wasn't for Mrs. Holmes and his father-in-law, the younger brother would not have returned to the British government in London.

It's just that Mycroft waited for his brother, but he shrunk down, and he was more immature than the fifteen-year-old Sherlock in a moving photograph of Irene's specialty brought back from the wizarding world on his desk, which is really... What a surprise.

It is worth mentioning that in the photo brought back by the wizarding world, Sherlock with a schoolbag on his back, the most he did was to roll his eyes at his brother, so that Mycrof could "see things and think about people".

The little black car takes Erin and Sherlock to Belmeer Street, McCroft's residence. Mycroft returned ten minutes later, and the reunion of the brothers after a long absence had not happened at all. Sherlock crossed his arms around his chest and asked Mycroft, "You gave Mr. Ai's contact information to Mommy?" ”

Mycroft looked down at his young brother, and was silent.

In less than ten seconds, Sherlock exploded, and he looked like he was rushing up and scratching Mycroft's paw the next second.

Erin blinked and spoke slowly, "I want to remind you, Sherlock, that your body is only four years old now, and your magic is unstable. ”

Sherlock won't admit it: "I didn't." ”

"I know, but just in case, so you two talk slowly." With that, Erin left the space to the two brothers, Mycroft and Sherlock, who thought they needed to talk. But when she went to the room that Mycroft had signaled to her, in less than five minutes, Sherlock pushed the door open and came in, closed the door and stood by the door.

Erin turned her head to look at the voice, raised her eyebrows and didn't say anything, then turned back and continued to look at her phone, although the zombie vaccine research has entered the final testing stage, and there are also Dr. Banner and Tony, who has also become four years old, but Jarvis still dutifully sent a copy of the test progress.

Sherlock: "......"

- What a ruthless fiancée!

Sherlock froze for a moment, and seeing that Erin didn't mean anything to happen, he pretended to be nothing, and sat down on the chair next to Erin, and said dryly, "We're going to see John to-morrow, and Mycroft told me where he worked." ”

"Do you know that your modified anti-aging agent won't expire until nine o'clock tomorrow night, or do you want John to see a "strange disease" that has no precedent? Erin finally gave some attention to her fiancé, although this made Sherlock not so fond of listening, and he craned his neck to say something, but Erin turned her head and said, "No, I think the most important problem is that he thinks you're dead, Sherlock." I don't think he'll be happy to accept you from the dead without any nervousness. ”

Sherlock was clearly unimpressed: "Why not? ”

It turns out that Erin's emotional intelligence is higher than Sherlock's, and John is really not happy, and accepts the resurrection of the dead without any guilt, becoming a four-year-old Sherlock, he ...... He's broken!

――What should I say, what is there not a surprise in life?
