Cassie loves One Direction music, and she especially loves to sing it while she works out.
During a team workout after Arsenal joins the team, Cassie has her headphones on while she bench presses with Superboy and is singing 1D, and Arsenal starts laughing at her like "You actually like that crap?"
Cassie goes red with embarrassment and anger but before she can deck his lights out, Robin stands up and starts singing nervously but beautifully (thank you Cameron Bowen) along with the chorus, and soon enough Gar, Bart, and a reluctant Jaime are singing along to "Best Song Ever" and Arsenal just stomps off because now he's embarrassed.
BONUS: Cassie asks the others if they really like One Direction and Bart says his favorite member was Zayn because he looks like Jaime.
