[Grey considers the logistics of Manabu taking a shower, insomuch as he safely can. It's rather difficult to do so and avoid picturing Manabu naked, wet, Grey needing to help him lather up...

Nope. No, there's no chance Manabu would be willing to put up with that.]

I don't think you'll need much help, actually. You seem fine if you're sitting, and we have a detachable shower head and a stool. The only real concern is that you might fall getting in and out of the bathroom.

[And Grey can just see Manabu clonking his head on the sink...]

You can lean on me and I'll walk you to the shower, then I'll leave you in there to clean yourself up, and you'll call me back when you're done. Does that sound acceptable?
