JOANNA

Joanna: "Mia said Vivian was off drugs and going to meetings, trying to get it together. Why would she kill herself?"
Will: "Uh, she didn't. Even less relevant, why did you stop being friends?"
Joanna: "You know, just girl stuff. School stuff. Insurmountable class and race stuff."
Will: "You saidhate, you used the word hate."
Joanna: "I am about to have a flashback so fucking crucial I will have it twice."

TEEN FLASHBACK

Joanna followed Vivian out into the garage, where she was stumbly and barfy and smelled like booze. Vivian yelled -- presumably -- at Joanna to shut up, and then to distract her, started taunting her about Julian:

Vivian: "I know everyone thinks you're an angel, but I know about you and Julian. He doesn't care about you. He only bangs you when he's bored. And then he doesn't think about you again until the next time he's drunk and horny..."
Joanna: "Way harsh, Tai!"

Vivian booted and rallied, but before she could stop her Joanne ran off to get Robert Bowers. Just mentioning him scared more barf out of Vivian, but Joanna was so worried for her friend -- and ignorant of the actual situation, which again we already basically understand -- that she didn't listen. And I guess that was when they stopped being friends.

COP STUFF

Will: "Anyway, interesting flashback. Hey, do you want to go back to dating me again?"
Joanna: "Sorry, was I boring you? Uh, no. I broke up with you to let you off the hook. You had a great offer from the FBI... And I mean, we'd only been dating for a week."
Will: "Yeah, but we were partners for four years, so I always thought it was like prorated in some way..."
Joanna: "No, that is not how people work. Which is not to say I won't fuck you later in this episode."

SOFIA V. MIA

Mia: "Ugh, what. Why are you yelling."
Sofia: "-- I'm not talking about him, I'm talking about you.* You're not allowed to cut school..."
Mia: "Just go have another drink and forget about it, like you do everything else."
