Mariah would just ignore them…or if its someone who isn’t aware of her distaste for them and tries to talk to her, she would act polite on the surface but her responses would be short

Andre would do whatever he could to make that long elevator ride unbearable for them hehe

Person Odd Dislikes: (gets on elevator)

Odd: Mmm, no. (Warps Out)

And if Odd REALLY doesn't like them and is feeling spiteful, he'll warp the other person away instead-//

Kingston: silent bc he probably tried to close the elevator door before they could get in
Ruth: Stands in the corner avoiding eye contact

Death Glare from Fausto, he’s silent and just staring at them and when they speak up he just goes “shut the fuck up.”

Anyone Else: Will actively ignore them - pretending like they don't exist. Most likely on his custom Rotom Phone either playing games or looking at Pokétube videos n' shit. Alternatively, listening to his music. He's more or less in his lane and comfortably minding his business until he arrived at his floor.

Pokémon Hunter: Reflexively will try to stab them with his Aegislash or violently eliminate them using one of his other known killing methods. That elevator will most definitely be a murder scene.

"So... You play Clash of Clans?"

But for real, Tyler would probably try to ignore the guy and pretend they're not there. But if they say something, he'll just say something back, but not enough to warrant a fight
