Finding himself in strange dimensions at all hours of the day isn’t something new to Marco; thanks to Star, he’s been to places most other people on Earth will never get the chance to know about, let alone visit. Dimensional scissors are something Earth lacks natively, just as it lacks magic of it’s own. What has Marco nearing a breakdown now isn’t the fact that he’s someone other than Earth, it’s that he’s here suddenly; suddenly, and without Star, and without having used scissors, and without any idea how it happened or how he’ll get home.
From where he stands now, definitely inside of a a building, as he can see through a window, he can take a wild guess about where he’s ended up. Though he’d only caught a glimpse of the Underworld during the ball, he’s seen illustrations of it in Star’s book and he’s heard her describe it to him multiple times.
Squinting through the eyeholes on his mask, Marco emits a resigned sigh and slips the thing off, uncertain whether anyone would be willing to help him were he to go wandering about with it still on. With it off, his features begin to shift. Ignoring the discomfort as best he can, he places the mask safely into his book bag and then tugs one strap of it back over his shoulder.
When he turns, he’s surprised to see himself in-... a bedroom? Just his luck, of course. Not only does he wind up in a dimension he has no real knowledge of, he ends up in someone’s house. Good one, Diaz. How are you going to explain this one? Before he can even make an attempt at coming up with what certainly would have been an ingenious plan for getting out of this house unnoticed, the bedroom door opens and Marco, being Marco, freezes in place in the middle of the room, all four of his eyes wide as saucers.
