Riv: Seriously I can't keep fucking covering for you when you keep doing shit like this! One of these days I won't be there to catch you and you're going to fall flat on your face.

Em: Oh don't worry - if I'm falling, I'm grabbing onto you on the way! We'll fall on /our/ faces.

Em will do absolutely anything to prevent ever feeling fully alone again. She's angry that Riv thinks she's better (she assumes as much) and some part of her wants to drag her down to her level and show her she actually isn't so special after all

Key flaws: Riv will do just about anything to make others around her happy while trying to work toward deciding who she wants to be.

Em: the family fuckup, constantly failed to live up to expectations while stuck in her sister's shadow, lashed out at the world fairly destructively to try and establish any identity of her own, utterly terrified of losing what's left of her family and truly being alone

Em: *taking a big breath as if she's about to say a lot of things nobody here actually wants to know*

Riv: That was a /rhetorical/ question, asshole.
