Five can sense his confusion, but he hadn't used his ability to show off, or to prove that he's capable of more than appearances would dictate. Teleporting is not only how he captured the old man, but it's been how he's kept it from getting out, beyond a handful of people who were there in the beginning. And if it helps to keep Regulus from knowing exactly where he's keeping him, all the better. (Though honestly, if this doesn't work he's about had it with the whole wasted effort.)

"Just hold on." He latches onto his shoulder and tears another path through space, accounting for the extra mass displacement to take them both into the room he'd left a moment ago.

About half the people he teleports with get sick, so he gives Regulus a moment as he circles back around to the man who is tied loosely to a chair in the middle of what appears to be a shed. Previously he'd been in the bathing room, and the restraints are newly applied. The man looks angry, like he always does when he sees Five, but he doesn't seem horribly injured. He's also rather pointedly silent.

"I don't think he's one you've met." Five turns to eye Regulus, judging his reaction. There's no easy way to explain away what's obviously apparent, so he simply gestures to the restraints. "I didn't know if you needed him to hold still."
