Hah. Lost for words, is he? Riddle doesn't have a leg to stand on. He knows this isn't good for him; he's just reluctant to take the steps he needs, to reach for the help he needs, until he can rest easy with himself. Doesn't he already know what he should do, even if he's not willing to admit it to himself just yet?

Riddle's hand covers his mouth quite thoroughly, muffles his voice even if he does try to talk. So why should he, until he's actually able to be heard again? The way Trey smiles against Riddle's palm is the only warning he'll get, before Trey's legs tighten around Riddle's, before he rolls his whole weight to the side to switch out their positions. Who needs to push up against the pin, when they can add their opponent's weight to their own momentum instead?
