Steven, at the time of Gon knocking, is basically drooling on the daybed in the main area of the room he's been staying in, probably with a few others. He'd come back just to have a quick rest, but it went on for longer than expected.

Having a visitor startles him, but more in the way of suddenly realizing you've been sleeping when you didn't mean to, rather than being woken up at a bad time. It's only then that he realizes that some tiny, blossoming rose vines are also growing around him. He did not mean to do that.

"Um, coming!" Steven says, pushing himself up. He tries to spring off of the bed, but then the ache in his gut reminds him he still has some wounds there. So, instead, he grows out the viney portion of his arm to open the door without having to stand up.

"Actually, can you come in here?"
