Wren was happy enough to let Archie call the shots on his bath and mostly just relieved that he hadn't said something that warranted a punishment. He wasn't told to follow Archie into the bathroom, but he tensed when he heard the sound of water running and hitting porcelain - he didn't know much about the decadence of bubble baths, but he knew about being stripped down and pushed into a shower cubicle to be more rinsed off than showered down in the lukewarm water he was told to be thankful to have. When he was being 'difficult' they just hosed him down and left him dripping.
Archie returned with a smile though and although the sound of water running still echoed through from the bathroom, Wren couldn't help but smile back and lift his head with unearned trust to let his new friend remove his adornments. "Thank you." he murmured as Archie spoke to him, all the kind things the man was doing for him filling Wren's heart. He leaned into the fleeting touches where Archie's deft hands removing the flowers happened to touch against the skin of his face, nuzzling in like a cat.
The hand in his hair was unusual - he'd been so touch starved before now and he tended to be so dirty that even those who took pity enough to feed him didn't want to touch him - and it made him flinch for a second before turning his head in towards Archie's touch yet again. He couldn't remember being treated so gently or touched so readily before, at least in that moment.
"I couldn't wash my tshirt for a while." he agreed in a roundabout way, although what would be left of the thing after the dirt and grime holding it together was washed away only god knew. "I can, it's sit in the water and rub it on, right?" he checked, not sure about these mythical 'bubbles'
He followed Archie as docile as a lamb into the bathroom and the tension he'd felt before at the sound of water running eased when he saw it was just a small pool, and nothing he'd have to stand up and shiver in. He kept hold of Archie's hand as he eyed the bubbles though, still unsure, which was a good thing as he'd have just stripped off right there and then otherwise, any sense of modesty about his body long since scoured away. "Is that what they're for?" he asked, his uncertainty not letting him indulge his curiosity. "Hiding?"
