Adam is a nerdy high-schooler who likes making and watching movies. He likes Ghostbusters, ET, The Princess Bride, and The Goonies in particular. He is a nice kid, although he and his siblings often fight and have drama. Adam is a late bloomer, revealed in the episode "Cowboy Country".
Barry and Adam like a lot of the same things like the Beastie Boys and Ferris Bueller. However, Barry is always teasing Adam for what he considers "nerdy" things he does, such as always making videos and playing with action figures.
As revealed in one episode, Adam and his sister used to be very close when they were young. They started a detective agency where they often solved mysteries together. Sadly, now that Erica is grown up she refuses to remember those memories/hang out with Adam.
Dana Caldwell was Adam's first crush. He met her in the episode "The Ring" as his cute neighbor and tried to woo her by holding a boom box outside her window like the character in the movie "Say Anything." Later in the episode "You Opened the Door", Adam and Dana have their first school dance where they finally hook up. In, "You're Not Invited", he receives his first kiss when he dies for her in a game of laser tag.
