Tricky Old Teacher - Kira Roller put on a tail

Oh, for God's sake, where does she go? I can't leave because of this girl.

Finally. Yeah, yeah, come on in. Come in, sweetheart. Where have you been?

We'll identify you, pretty lady. You know, we've already missed an hour. I sent the other students away because of you.

I just didn't have time to learn anything. I just had her problems there.

Could you tell me what this is, please?
