"Good." That one word is ground out of his mouth between clenched teeth, like a cigarette under a boot. He won't look at it again, not here or now or in front of his brother. He sees the movement of Four's hand and, unsure if he's going to try to reach for him not, Diego instinctually shifts his weigh to his back foot, to make it obvious he doesn't want it, if that's the intention. Thankfully, he wraps his fingers around that chain at his neck instead.

A part of him wants to end it, to let that be it, and he debates for a long moment about turning on his heel and leaving the room. But no. Klaus had still not answered two of the biggest questions he'd asked before, and Diego decides he doesn't get to not. So he waits a moment before he finally reiterates, "What happened...between you and Allison that's made you...be this way toward her?" He asks again, finally looking at Klaus again, eyes on him more in a fashion of a sniper on a target than simply looking at him. "And when do you stop making the same choices over and over, expecting it to turn out different next time?"
