Class had just started. You're already in class, so it's fine. The teacher was just about to say something before Doll heads into the classroom.

Teacher: "Doll, why are you late?"

Doll: «я был занят.»("I was busy.") She says apologetically and heads to her desk, wiping a bit of oil off the side of her mouth. Her friend, Lizzy, teases her about being late.

The teacher sighs and begins the class.
