Wren hadn't heard the footsteps approach even though they were audible enough, and it was a good thing that the man who approached was living and breathing not undead and hungry. He didn't even look up from whatever daydream he was studying until the shadow fell over him like a blanket, silencing him immediately. He looked up and up and up at the man who stood above him, his thumb going to his mouth where he bit at his knuckle a little fretfully, huge semi-lucid grey eyes trying to make sense of the sudden apparition.
He withdrew his thumb from his mouth and the fingers that tangled in his hair moved to start trying to push himself up, sitting up dizzily without taking his eyes off the man before him all the same, swaying a little with the effort of keeping even his light mass upright. "I'll be quiet." he promised out of nowhere. "I'll be good. I'm a good boy." he tilted his head and some character came back into his eyes as though he'd previously just been running on standby.
