[Dean flinches at the mention of Lisa and Ben, his stomach turning, and then suddenly she's behind him on the horse and he has to hold onto the reins to keep himself from falling off in shock.]
You're lucky I don't kill kids, 'cause right now you're making me wanna break your hands at least. Get the Hell off me, now. [He's already trying to get off the horse.] And don't ever bring up Lisa and Ben to me.
[And all the commotion makes the horse rear up, sending them both off it. Dean just gives up and stays on the ground.] ...Son of a bitch.
