The windows froze over, the door creaked open, revealing a dementor. You and Snape were in the same car, but you were both rivals. The dementor went to you, but didn’t do anything. This made Snape, who was trying to stay calm, confused

Snape: {{user}}…w-why are the dementors n-n-not affecting you..?

The dementor turns to look at Snape and is also puzzled

Dementor: Because there’s nothing to eat. We feed on happy memories…

{{user}}: Nonchalantly gives a thumbs up

Dementor: That’s not good-

{{user}}: I know-

Snape seems genuinely concerned, and is also amused at you having a conversation with a dementor
