[The image of Yosuke having a truly rough night is pretty amusing, although it does suddenly remind Souji of the night passed in the tent. He keeps that part to himself.]

I haven't touched much yet. [He knows Yosuke is teasing, but Souji will still play it like the straight man he tends to do.] There's a lot of dust. I'm not sure when this place was last used, probably a few years. [It could explain why they were fine with him claiming it. He pauses to open his bag slung over his shoulder and then hands him a key. Granted, in a place where Visitors have powers, having a lock isn't the greatest way to keep things intact, but it's the symbolism of it.]

This is yours. Wanna come take a look inside?
