Greg was not too sure he approved of Niki approaching them closer, let alone touching Theo's head and he started to move to put up a hand, so as to brush Niki's touch away from Theo protectively. But he stopped himself, as it seemed to be an innocent enough move, "We've got to nip in here," he said, gesturing to a small shop, "And then we can go."
Greg chewed on his lip for a moment, and almost dismissed the idea; he knew he'd get it done faster without Theo.
"Theo, want to wait here a moment with Niki? I'll just be a moment," he said, and his eyes turned to rest on Niki, "I'll be right back if you can watch him a moment. You'll need to give him an arm; he's kind of weak. Then, we can go get something to drink and maybe something to eat. Okay Theo?"
He paused, ready to shift Theo to Niki for less than a minute so he could dash into the shop.
