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.
