Season 1

A Time to Travel

In the pilot episode, Barry heard Shelby and Cyd knock meaning that they wanted something. Barry opened the door and the girls stepped into the RV. Shelby and Cyd then saw Naldo who was working with chemicals. Barry told Naldo that he shouldn't mix those or something bad might happen but he didn't listen. Shelby then changed the subject and told Barry if the "big ask" parade was going to happen. Barry said yes and guided through instructions. After that, Barry and Naldo leave to test their new invention. Cyd is hungry so she peeks into a machine made by Barry but it isn't a fridge. Cyd is furious and then the blast comes and makes the girls time travel. Afterwards, Barry doesn't appear until he tells Cyd that the machine might've done anything.
Cyd disagrees but Barry knows Cyd was lying. Afterwards at the lab, Barry helps Cyd get her emotional out of Shelby. It doesn't help but then Barry and Naldo go to the Blast Box and test their new invention. Cyd and Shelby then apologize and think back to morning and then Barry is happy that Shelby and Cyd are using time travel.

Barry is extremely smart and loves to learn new things; however, he is also socially awkward and has trouble talking to girls. He is a little jealous of the fact that Shelby and Cyd discovered time travel and wants to recreate it so that he can take credit. He has a strong love for science, and nearly everything he does is done in the name of advancing it.

Barry is something of a stoic and is not one to get emotional or excited. Preferring to remain calm and casual. He normally will only get emotional in life-threatening emergencies. He's shown to have trouble recognizing facial expressions and social cues, can't match emotions to faces and lacks several social skills. Except in genuinely important or serious matters. Back when he was in 6th grade, he was very socially awkward to the point where he hid in a trash can to prevent being "Blasted" by ruthless mean girls, and he was known for crying a lot.

Barry is highly logical and normally thinks through matters before doing anything. Barry is the manly man to Naldo's sensitive guy. Granted Barry isn't a traditional manly man, however, he still qualifies down to the fact of the two of them he is the more dominant, decisive, hard-working, focused, practical and capable (he did after build all his technology himself). He likewise is very bad when having to deal with emotional issues.

While highly intelligent and mature, Barry will occasionally show that at heart that he is still a teenager. Such as agreeing with Naldo his taunt would be a good name for a band, and playing a prank on the country club involving rats, in response to getting kicked out.

Although it seems Barry will do almost anything to make a scientific breakthrough, he is too moral and caring to be willing to hurt others to achieve his goal. This is shown when he told Janet that hurting Shelby and Cyd wasn't worth making a great discovery, despite not knowing the girls in the alternate timeline. He's likewise clearly disgusted by Janet's lack of moral scruples.

Likewise, despite his stoicism, Barry is truly a good friend. He doesn't always show it, but he appreciates those who care for him and will always come through for them when they need him.
