lilah would love her right back! they were first in nick and norah together, though i can't remember if they shared any scenes, but maybe they bonded just from being around set or they could have somehow never met and realized while they were doing pitch perfect that they'd been two ships passing for years because they were always auditioning for each other's parts or something and now it's become a big joke that they're star-crossed besties and always flying into a city when the other's about to leave or something?
