Pain has become something that Rung is all too familiar with but, this sort of pain? This sort of pain is rather new...and a lot worse than anything else he'd ever really experienced.

His optics flare when the other first clamps down, his hands grabbing at Dead End's upper arms as the pain shoots through him. He manages to not struggle or jerk though, reminding himself that he's doing this to help the other, to show Dead End that he cares and does trust him.

Pulling away now would make that all null and void.

But Primus did it hurt. His optics dim a bit as his frame trembles, the therapist doing his best to stay upright, to keep hanging onto the other but it's hard.

Really hard.
