Wren was sure that things were going to go the way he expected them to when his new friend stopped, even if he was a little worried at the growling, but he was shocked neatly out of kissing when his legs were dropped. He wasn't quite sure what he was supposed to be doing and wondered if that meant he should drop down to his feet, but then the man took hold of his wrists and he whimpered a little, not wholly in the farce of seduction he'd been making. His hands went from touching to clinging and he waited for that grip to turn hard, to leave bruises or maybe break his bones - it would be a hard thing to do even though his bones were weak and brittle from malnourishment even pre-apolocalypse years but they'd been broken before as well and he was sure they'd be broken again.
He braced for the snap but the one that came was worse. He cringed when he was told to stop, bewildered and unsure as to what he'd done wrong and what to do now and what the man meant by what he'd said. The protests from his dad and brothers, from any man he'd made advances to before had never made sense to him. He squirmed to get himself back on the man's back securely when he introduced himself and Wren paused again. "Sarge? Sarge, Sarge." he repeated to himself, trying to close the name up in the little book that was his memory, even if it was prone to gaping open and letting everything inside slip out. "Hallo Sarge, I'm Wren." he said again, like he hadn't introduced himself already. He curled his fingers tight into the man's shirt and that stopped his hands moving. "Thank you for... thank you." he said softly, not sure how to communicate his gratitude from his current position.
