It was only after Barry had completely solved the problem that had affected his emotions that the situation had developed further, which they had never imagined.

"Barry, you're doing a great job, you're in control of your emotions, and you're a good choice." Qin Tian looked at Barry and said solemnly, it was also the situation they understood.

"Thank you, Mr. Donners." Barry looked at Qin Tian and said gratefully, for that kind of thing, it is also recommended to consider.

The sudden phone call calls Joe away, leaving Barry and Iris at home to pick up the presents. Barry ingeniously gave Iris a necklace, a replica of his mother's necklace that she lost in the fifth grade. That day, Eddie proposed to Iris, and Iris happily agreed. That night, as Caitring returned home, he saw an unkempt man in the reflection of the car window, and when Caitlin followed, the man spontaneously combusted. In the crystal lab, a yellow shadow that suddenly appears attacks the police, fleeing after searching for something in vain.

"Barry, I'll tell you something, that guy may be there, a yellow shadow." Joe looked at Barry and said solemnly.

"What's the situation?" Barry said in surprise, and there was anger in his eyes, and no one was more angry about these things than Barry.

"I'm looking for those cases, and there are situations that need to be considered for us." Joe looked at Barry and said solemnly, knowing what to do.

"You'll be fine if you're okay, Joe." Barry looked at Joe, nodded and said, these are the aspects they control.

Barry is convinced that his mother's killer has appeared. Joe is embarrassed to tell Barry that he is threatened. The case was analyzed by the Cutting-Edge Labs, who believed that the tachyon being studied by the Crystal Labs was the object of the Yellow Shadowman's search. Dr. Wells and Barry approach Dr. Rogie at Crystal Labs, hoping to use her research as bait, but are rejected. Kate thinks the burning man is Roddy, and she tells Sisko and hopes he can help her. Looking at the evidence in front of me, I recalled the bits and pieces of my childhood and my parents, and unconsciously had nightmares.

"Barry, what have you been up to lately, can you tell me?" Iris looked at Barry and said solemnly, hoping to get Barry's affirmation.

"No, I can't tell you, that's what I'm thinking about." Barry looked at Iris, shook his head, and said, "That's what they understand."

"I still have something to do, I'll see you when I have time!" Barry waved his hand and said lightly, and they understood the situation.

Iris feels a little strange about her relationship with Barry lately, and she thinks that Barry is hiding something from her, so she decides to ask Barry herself. Barry discourages his feelings for Iris. After Iris left, Barry sees the Yellow Shadow and chases after him, but Barry is still close to him. In the end, the Yellow Shadow Man arrives at a track and field field, and Barry has been at a disadvantage in the confrontation between the two, and finally the Yellow Shadow Man leaves a few words and leaves.

"Barry, you're still so weak, your speed can't match mine, it's like you're not blocking me, and that's something I know well." Reverse Lightning looked at Barry and said solemnly.

"Who the hell are you and why do you have such speed?" Barry said in surprise that they were fully aware of such a thing, something they couldn't have imagined.

"I can't tell you now, but you'll have a chance then." Reverse Lightning said coldly, in the face of such an advantage, Barry has no way at all, any idea is like that.

"Really? I'll definitely fix you. Barry said fiercely, facing that kind of situation, which is also something they want to solve.

The next day, Barry told the people at the cutting-edge lab what he had seen. Eddie's special team to arrest the Flash came down and told Iris about it, and Joe was helpless and angry. With Sisko's help, Caitlin and Sisko find Roddy, who no longer knows the two and refuses to approach them. Caitlin was so sad that she couldn't stop crying. Barry managed to get Dr. Rogie's consent to get the tachyon model, only to be told that Dr. Wells and Joe were not going to involve him in the matter. Barry is furious and blames Joe for hiding it because he was afraid of being cowardly. He simply went to the prison to find his father, he told his father about his fight with the Yellow Shadow Man, and felt very guilty that he had messed it all up, and his father advised Barry to let go of the matter and not let his life get lost again, and Barry listened to his father's advice.

That night, Barry confessed to Iris without hesitation, and he told all the love and affection he had for Iris for more than ten years, and Iris was also shocked by this sudden event. In the cutting-edge laboratory, the trap set for the Yellow Shadow Man finally worked, and the Yellow Shadow Man was trapped, but just as Dr. Wells and the Yellow Shadow Man were talking, the trap they set was destroyed by the Yellow Shadow Man, and the Yellow Shadow Man grabbed Dr. Wells and beat him violently, and in a hurry, Joe broke the barrier, but unfortunately the Yellow Shadow Man knocked everyone down on the spot, except for Joe and Eddie.

"It's great that I've finally found you." Barry said solemnly, looking at the reverse lightning with unforgettable anger in his eyes, which was also something Barry felt.

"Whether you come or not, Barry has no effect on me for the time being." Reverse Lightning was not afraid of Barry at all, looked at Barry, and said lightly.

"Then I think it may be you who fails, I have so many friends, you are definitely not my opponent." Barry said with certainty, and he was quite clear about their considerations.

"You can call me Reverse Lightning, a great name, can't you?" Reverse Lightning looked at Barry and said lightly, without fear at all.

At this time, the Flash arrived, and although Joe avoided danger, he was completely controlled by the Yellow Shadow Man and let him beat him, and then the Yellow Shadow Man was forced to leave. Add warns Caitlyn not to look for him again. Eddie asks Joe again and again what he is hiding from him, and in desperation, Joe tells Eddie about the superpower, but does not reveal Barry's true identity. Barry apologized like Joe, apologizing for what he said on the impulse today. And Joe also revealed his true feelings. The two are as close as father and son.
