"Mmhm," Martin answers softly, letting his shoulders slump and his eyes fall shut for a moment. The water and heat are certainly treating him nicer than anything else has so far; and it's comforting to have John with him, too. But as he looks at John again, at his slightly awkward positioning against the tub, a little spike of guilt rises up and he says, "S-sorry to make you, er..."

He trails off with an embarrassed shrug. John will surely dismiss his concerns, such that it almost feels pointless to have aired them at all, but it's too late now. He hates being a bother, and it's still difficult not to see this as somehow burdensome. Apology is an impulse he can't quite shake, not even with John smiling at him like that.
