He gasps softly at the hug, because while he's grown to accept it from Bill and Nardole, it's still hard to believe others would want to.

And he might cling to her just a little bit tighter at that thought. He misses them. He hopes Nardole is alive, but he has no way to know for sure and Bill, well, she gave her life to save others. Taking too much after him like everyone.

And he will not let himself cry just yet. He'll squeeze her tighter again, before loosening his hold to let her know to let him go.

When he backs away is when he notices a smudge of soot on her clothes and he looks down at himself.

"Oh dear me, I didn't even think..." He looks up at her, not scared but a bit worried about how she'll react. "I'm sorry. I'm... There was this fire, burned the entire floor. Including me and my clothes."

He kind of holds them up to show they're covered in soot and ash.
