[It doesn't startle him, since he's used to Shotaro and Akiko just barging into the basement while he's doing things. He pushes himself up, which takes some effort. He was comfortable and only now that he has to get up again does he realize how tired he is.]

...Thank you.

[He takes the food and eats, trying to keep himself at an okay pace.]

I just want to get everyone home. So I'm trying to work really hard, for everyone. I don't want to let anyone down.
