Hahaha, I like Cass's hallucinations. Bruce comes off as the Dad that expects you to always get good grades, pass in all subjects, Babara comes off as the over bearing mother-figure "My poor, baby" and Tim & co. comes across as the traditional High School teenagers while Nightwing seems like some sort of uncle/big brother type, he is the only one aside from Bruce/Cain/Babs to not make a joke about Cass's body.
Say Bruce you might want to meet General Lane for a beer to discuss about parenting young girls.
