Roomies is the third webisode of season one.
Wonder Woman is awoken by a horn honking, which is revealed to be Harley Quinn celebrating their first day of being roommates. While getting dressed, Harley sneaks up on Wondy and gets knocked into her wardrobe, getting entangled in the Lasso of Truth and admitting that she clogged a toilet last week. After this, Wondy starts decorating her dorm space, and Harley decides to help by throwing a glitter bomb at the wall. Wonder Woman blocks it but gets covered in yellow and pink glitter. Harley then comments that Wonder Woman's book looks boring, but she says its for studying for math. After telling Harley to let her be in peace, Harley glumly goes to her side of the dorm and sits sadly on her bed. Wonder Woman then decides to ask Harley if she wants to hang out, causing Harley to hug her in delight.
