Sebastian’s having so much fun, then he sees that Kurt is there and his face just changes. His face just drops to annoyed/irritated/ugg.
First of all, how dare Kurt take the smile off my child’s face. Secondly, did Sebastian like forget Kurt was there and the reminder ruined his mood for a second? or did Kurt’s uncomfortable staring, demeanor, and just being a wet blanket do that.
I kinda think it’s a mixture of the two. Like Seb was thinking, “Ugh this guy exists and not only is he in the way, but he’s boring af and dragging the mood down. How is this sex-on-a-stick into him?”
(The gif took a ridiculous amount of time to make. Literally an hour or two, no exaggeration for once. I already had a gif of this, but it was apparently to big, so adjustments had to be made. I spent like an hour and a half trying to make it small enough for Tumblr. But the site I was using not being helpful, Tumblr saying that it was still “too big” or that there was an “error”, downloading failures, internet not working, the site I was using being annoying, etc. I eventually gave up and remade the gif from scratch.)
