"How were you supposed to know what he'd do to you?" There's the obvious analogy between what Hilmi has and STIs, but Steph actually has no idea a) if Megan used protection, or b) if condoms actually work against magical addictive dicks.

"You don't really look like you are." Sometimes honesty is the best way to deal with situations, and Steph feels like it's necessary now. Megan looks like shit, and she doubts repressing it will make things better.
