I do have several conerns about Chris being on a plane. From personal travel experience, I know how taxing travel can be.
1.) If Chris's weight/girth is as big as it appears to be, depending on the airline I do hope he asks for a seat belt extender. If he doesn't that's going to be a disaster in of itself as he'd probably refuse to get one because he believes that he's "slim" and "trim".
2.) The person who sits next to Chris will probably need to hopefully have a lot of patience to be around him. Especially if he belches, farts and stress sighs during the whole flight.
3.) I know Chris would be selfish but I pray he won't assume that an in-flight meal delivered to his seatmate is for him too and takes it. If anything that'd be enough to start a shouting match with Chris reeing that his neighbor was being naive, selfish, and against the SLGBTQ+ community.
4.) if he does have a seatmate will he ree about Magi-Chan, or Cryzel sitting in the seat next to him? Like will he ree out and say that the person who has to sit next to him in the other 2 seats is taking the seats belonging to his heartsweets?
5.) Will Chris demand to be seated in First Class if no one sees him as a super spechul goddess? Or will he ree out if his seatmates are black?
These are things that worry me about Chris being on a flight without supervision. And I feel bad for any of the female flight crew having to deal with his advances. But who knows maybe the flight will have all-male flight staff and Chris will sit down and be quiet.
