"Of course," Archie agreed readily to staying close by to talk. If the bubbles were thick enough for the time being he could even remain in the bathroom and talk to Wren from there.
He took Wren's shirt without question, moving it to the bedroom so that he could take it to be washed when he got the chance. There were towels and things already in the bathroom, so he could wrap Wren up before they found something for him to wear. Archie again made no comment about Wren's appearance, about how thin he was (he was living in a forest, he was hardly going to be healthy) nor the marks on his skin (because Wren lived in the forest. It wasn't as though he was being looked after, or had anyone to take care of him) because right now Wren was in his company, so he was safe. There was nothing Archie could do about the past.
He sat himself down on the closed toilet seat, watching, pleased that Wren was enjoying himself. "I don't usually have baths. But when I do, I do like to have them with bubbles. It's relaxing. I know some people have fancy oils and things, but I think the bubbles smell fine as they are."
Archie stood and reached for the shower gel perched on the side of the bath. "You can use this to wash with. Use as much as you like. If the water gets too dirty we can run you another one," he nodded, kicking off his shoes into his bedroom, and his socks, resuming his seat on the toilet.
"Do you think you can remember how to get here, Wren? To my room? In case you need to. Or if you want to. If I'm not here, if I'm at work, you can come in and wait." He would tell Eli. Eli was gentle and kind, despite whatever outward appearance he wanted to give. Then Eli could take care of Wren when Archie was out.
