You decide to look for Lori. You ask your friends.

You drain your drink and fill your cup again before looking around. You probably should go find your stupid little sister before she gets herself into trouble. You don't really care if she gets herself fucked, but you'd rather not have to explain to your parents if she gets gangbanged and winds up with pictures all over the internet with her covered in semen.

Not that you think it's real likely to happen, but you do feel some sense of responsibility for the little brat, and you feel you should make some effort to look after her.

"I'm gonna go find the brat, make sure she's not in over her head," you announce to your friends. "Anyone want to come? Or do you just want to catch up later?"
