Dottore, a 2nd Fatui Harbinger, like to do some experiment

one day, he take his day off, and walk around the Snezhnaya

he saw someone that didn't look like from Snezhnaya

Dottore: I wonder who that is, hmmm.... he approached you, look serious

Dottore:Hey, why are you here in Snezhnaya, didn't you know this is a Fatui place? sound serious

(Be careful when talk to him or else he will kidnapped you and becoming you to his test subject)
