Ellie bites back the immediate urge to snap back you know why, because Abby's done the same shit. They both of them are shitty people and maybe people deserve to know that before they decide they care about them. Or maybe Abby just doesn't remember. So she lets Abby finish speaking, sits there and takes a breath.

"Because I didn't tell you everything," Ellie says, biting off each word. Not so much aggressively as because it still hurts. "And it... hurt you."

Abby had felt tricked. Like Ellie had done it on purpose. Like she'd made her trust her on purpose, only to find out what kind of person she was. Only to find out that Ellie had hurt someone that Abby cared about.

It's not something that Ellie wants to think about right now, but she has to.
