|Relationship||Serena (broken up, twice)|
|First Appearance||The Big Sickie|
Chad is first seen in "The Big Sickie." There, he allowed Wyatt to leave work early after Wyatt claimed an overdose of Pixie Hicks, and along the way revealed some of his preferences in music (suggesting Coldplay and Talking Heads to help with rehabilitation.) After that, though, he mainly served as a background character who also happened to be Wyatt's co-worker.
His backstory was fleshed out a bit more in "Bring It On" when Wyatt learned that Serena used to date him. This shocked Wyatt, but he eventually got over it. However, in "The One with the Text Message" Serena broke up with Wyatt through text in order to get back together with Chad. When Wyatt asked why this was, Serena said that it happened over the senior trip to Paris and she was going back to Chad because she thought that Chad was more mature than Wyatt.
Despite this assertion, Chad does not seem to be mature so much as dim. Chad has a relaxed temperament and rarely gets upset, but this is because, in Wyatt's words, "he's so chill he has permanent brain freeze." He seems to be very self-absorbed, and not cognizant of much outside the world of music and his current life. This self-absorption actually drives the plot of "Midnight Madness," as he purchases a single ticket to a concert on New Year's Day and plans to leave Serena alone on that night in order to see the concert. (He does eventually change his mind and choose to spend New Year's Day with Serena instead.)
Chad has decreased precipitously in importance as a character since the conclusion of "Midnight Madness," as Wyatt no longer worked at Spin This (as of "Going Underground") and Serena quit spending time with Wyatt. He reappeared in a few episodes after that, but wasn't important until "Love At Worst Sight," when Serena considered cheating on him with Wyatt. In "Kylie Smylie," Serena revealed that she and Chad have broken up.
- Even Chad felt that it was low of Serena to break up with Wyatt through text message.
