Wren chewed at his thumb a little when he heard that. "I don't have a house and bath but I would look after someone you cared about." he said eventually, although how well that would go was another matter. "I would look after you too!" he added a little brighter.
He nervously bit at his lip now as poor Archie tired to parse out his next question. "I don't... I don't want to go to the dark room." he tried to clarify, sinking into the water a little like it could hide him or keep him safe the more he was immersed. "That's all, I don't like-" he broke off there and shook his head like water had gotten into his ear, and it was probably for the best that he didn't finish that sentence.
He let Archie reassure him though, the little dark cloud that had come over him dissipating slightly. "I don't know what over-imposing is." he said, as though he'd be scolded or ridiculed for that. "But you make me comfortable. I'm happy I can talk to you and I am happy in my bath!" he smiled and rubbed at his chest again, the water he was sitting in now opaque with grey. "I feel safe with you Archie, you're my friend. I like you to be comfortable too, you can take your clothes off if you like." he assured as he made some effort at rubbing the dirt from his skin. His face was half grubby now where he'd sunk into the water up to his nose, his hair dripping where the long ends had gotten wet and the rest of him some smudged version of clean.
