Rose thinking this thing they have is fun, a good way to pass the time on missions, and gives her a thrill sometimes. Meanwhile every time they kiss it takes Cass longer and longer to stop thinking about it. She takes a punch to the jaw because she's so distracted and when Rose laughs at her all Cass can think about is kissing the smirk off her face. But she doesn't get the chance to before they part ways and Rose doesn't even notice how Cass can't stop staring.

Cass: Barbara I need a way to stop having feelings for someone. Spell, potion, science. Please.

Babs, blinking away sleep because Cass broke into the clocktower at 4am: Do you want to maybe... Slow down and talk about it?
