"Lying bastard." She spits the insult quietly but with intense venom. There's still some thin pretension at civility here, under her rising temper and temperature. "Not only did you take advantage of my guilt and let me waste my time trying to repay you for your own crime, but you actually used me- to sleep with me."

It's kind of hilarious, how much angrier she is about that. On some level, Prue's aware of this, how ridiculous it is. That's the thing, though- being lied to by monsters she can take, that's almost a normal Tuesday for her. Betrayals due to magical fiascos are part of her life. But the last time she trusted someone enough to stay with them for this long and share this much of herself was years ago, with the man whose death she's still getting over, and Prue- Prue does not handle betrayal well. Not on a personal level. She took so long to defrost and get serious with him precisely out of terror that some stupid fucking Core thing would happen that would ruin their relationship, and here it is. In the instant of realization, she doesn't just realize what this contemptible shade of Sam did, she realizes that she's been fucked over again, and burned again, as the price for being trusting enough to fall in love.

She waits for his answer for about three seconds, but after realizing that fuck that, sends him flying into the wall with a wave of her hand.
