Joe's family discusses Harrison's affairs, Joe and Sisko plan to go to Star City to investigate the car accident that year, Sisko asks Caitlin to cover for him at Harrison's, Caitlin is very reluctant.

"Caitlin, you have to listen to me, Dr. Wells I have discovered a lot of secrets, you have to cover me, or I will be in danger." Simon looked at Caitlyn and said lightly, these are the things he wants to talk about.

"I can't do that, because Dr. Wells, he's not the enemy to go, he's not just our boss, he's our friend." Caitlyn shook her head and said that for that situation, it wasn't a problem they had in mind at all.

"I also know this, you can't have the heart to hurt others, and you can't have the heart to prevent people. You should know this! Simon looked at Caitlyn and said lightly, it was also the situation they thought of, otherwise everything would be something they couldn't control.

In a work building, a lady was working overtime late in the night, and when he was the only one left in the company, she didn't know that she was being monitored. She was caught by the police for theft, but in the face of surveillance, the woman said that the woman in Jianlong was not herself, and the people at the Institute of Advanced Science and Technology suspected that she had superpowers.

"Barry, it's strange again, we have to do it our way, or it's not like we're thinking at all." Joe looked at Barry and said solemnly, for that kind of situation, it was not what they thought of at all, everything was also developing, otherwise there would be nothing to say at all.

"Joe, what's the matter, we'll be here right away." Barry said simply, they knew exactly what was going on.

The police station received a call that a jewelry store saw someone selling stolen jewelry, and Eddie immediately rushed to the jewelry store. He failed to catch the man holding the stolen jewelry, and when Barry arrived, he was surprised to find that the man could change his appearance at will. He told his colleagues in the cutting-edge lab what he had seen, and they reminded him that he must not let the shapeshifters touch him, or his true identity will be revealed.

"Dr. Wells, I've developed a big secret, and this is quite important." Barry said lightly to Caitlin, obviously knowing where his usefulness was.

"What's the matter, Barry, you can keep telling me." Dr. Wells said lightly, apparently understanding what was good for him.

"I found that the superpower can be lifted to copy our appearance, and he can become us." Barry said solemnly, he also knew that things were getting more and more complicated, otherwise it would not be the situation they thought of at all.

"I see, Barry, get there!" Caitlin said lightly, these are also the questions they have in mind.

Joe's case at the Star City police station Chattes, Joe also asked to go to the scene to see it, at this time the daughter of the person in charge of the Star City police station appeared, looked at Sisko, and recognized Sisko as the person who was with Barry Allen, and she wanted to talk to Sisko alone. She says she knows Barry when the Flash, Oliver is Green Arrow, and herself is the Black Canary.

She said she needed Sisko's help modifying her sonic device, and Sisko was happy to help. Caitlin is upset about Barry's affairs, and she is angry that Barry would be suspicious of Harrison.

In the evening, Harrison returns to his house, Caitlin rings the doorbell, and a second before Harrison opens the door, Barry appears and takes Caitlin away at the speed of light. It turns out that Barry has been spying on Caitling, Caitlin says that she can't watch everyone ruin everything, and she is also afraid to accept the fact that Harrison is really the murderer, and Barry begs Caitlin not to leak secrets, even if it is to save his father.

"We have found out that the current situation is quite unfavorable for us, but we can't give up, and these are things we can't think of." Barry said solemnly, his tone was full of solemnity, these are also the things they thought of, and everything is in the process of development.

"Good, we have to succeed, we can't fail." Caitlin also thought about it, and they knew how to write things in that case.

Eddie and Barry find out about Hannibal's family, and when they go to Hannibal's grandmother's house, the old man is old and has no clear memory, and during the time when the woman makes coffee for them, the grandmother turns into another person and runs away, Barry and Eddie realize that it is too late, Hannibal takes the form of Eddie and hits the police officer and escapes.

In the end, Add could be imprisoned for this. Iris rushed to the police station nervously when he learned the news, and Barry promised to take care of the matter. Joe and Sisko bring high technology, and during a site survey, Sisko finds examples of speeding.

Eddie faces suspicion, Barry wants to rescue Eddie, Eddie doesn't allow it, and wants Barry to save himself in the right way, so Eddie continues to stay under house arrest, and Barry acts alone. Barry is at home and is about to go out, when Eddie suddenly knocks on the door, Barry doesn't realize the danger and is knocked unconscious, and Hannibal transforms into Barry.

"Hehehe, do you think you've won? Otherwise, it would not be a case of choice for us at all. Hanbani looked at Barry and said lightly, for Barry, he is not attacking anymore, these are also the situations he understands. ”

"Barry, you're here, we have a new way of thinking, otherwise we wouldn't have thought of writing things." Caitlyn looked at Barry and said solemnly, it was also something they thought of, everything was also changing, and nothing else could have happened.

At this time, Caitlin came over and said that he had found a way to stop the shapeshifters, and Caitlin didn't realize that Barry in front of him was not the real Barry. Joe and Sisko dug up bodies underground at the site, and this will be evidence.

"Let's go there! Let me see the evidence! Fake Barry said lightly, looking relaxed, it was not the original situation at all.

Caitlin takes the fake Barry to the cutting-edge lab, and the fake Barry behaves strangely and looks at Caitlin in surprise. At this time, Iris arrives, she is in a hurry to find Barry, and she finds a lot of evidence to prove that Eddie is innocent, such as the person who shoots in the video is left-handed, but Eddie is not.

Caitlin's situation, they can't think of writing things, is it Barry, Dr. Wells can feel that as a reverse lightning, he is also worth enough, otherwise it is also something they pay attention to.
