Dave's jaw clenches, the cold fear is in his veins and it's a valid thing to feel when Dirk starts talking like this. This is every bad memory of him and this is the Dirk that Dave is more used to. "Yes." he answers to the first question, "No." to the second, if Dirk was upset that he wasn't giving him straight answers, well now he is.

He stands no chance when Dirk wants to do something, Dave is a lot faster than he used to be but not as fast as Dirk. No one is. He might be able to out speed him through time, but he'd have to be ready for it and he wasn't ready for it. Being grabbed and set back into the apartment is fine, that means there's a connection there and Dave reaches back to grab his wrist and jump them both back in, closer to the kitchen window. "I didn't call you a liar, I said I don't believe you. You're the one sayin' I did." he's let go of Dirk's wrist as soon as they're back in. He's using future timelines so he doesn't end up making clones. "I'm not askin' for the world on a platter and I'm not askin' for a fight."

He tries to steel himself again and takes a deep breath, "Just say you're gonna and I'll get out of your way." Otherwise he won't and they can fight it out like they were destined to from the start.
