Being told he could just keep whatever clothes Archie might find for him was a sign of generosity so large that Wren was bewildered by it and could barely squeak out a 'thank you' - the only thing he had for the wash was the tshirt he was wearing and the only real value it had was sentimental, and even that wasn't much. He'd probably need a hand with his hair and all the different soaps that he might use for it, his previous dips in the lake not really the same as using shampoo and conditioner to get his semi-matted hair into something more comfortable and clean.
Archie explained the use of the bubbles and Wren was again taken aback by the man's generosity, wasting such luxury on him. "Archie, thank you so much. This is so much for me, lovely bubbles and everything, thank you!" he gave Archie's arm another hug before he stepped away enough to pull his tshirt off, leaving him immediately bare. "I, please, I like to talk to you." Wren asked, nearly begged, when Archie suggested leaving; as much as the bath wasn't a shower, and as nice as the bathroom and the bubbles were, the place was still a little too like a cell or the small room he didn't quite remember for him to feel comfortable being alone in it.
His body exposed showed how very thin he was, his bones pushing out under the skin everywhere, his spine when he turned a visible strip of hills and valleys. His skin was scarred from his rough way of life, small lines here and there from run-ins with pieces of wood, falls onto stone and various other woodland mishaps, but those silvered lines that spoke of older scars also spoke of different injuries; the outline of someone's teeth against his shoulder, cigarette burns in the soft parts of his arm, straight lines marching their way down his lower back and upper thigh too calculated and straight to be anything other than man-made, the ghost of another bitemark just glimpsed on the inside of his thigh as he lifted his leg to step into the bath.
He hissed when the water met the newand old wounds on his feet from going barefoot, sank slowly to sit in the tub and then snuggled down under the bubbles, lifting a handful to inspect them, fascinated. "Do you do baths with bubbles?" he asked, transfixed.
