After trying for several minutes to build up certainty that her voice is still working, Karen finally settles on a girl who looks like she's trying to avoid or escape from some other group's internal drama, and who therefore might (maybe, possibly) welcome an excuse to talk to someone else.

"Hey," she says, although it sounds more like a whisper than she means for it to. "Do you, uh, know what's going on?"

Hopefully that's vague enough that it won't be completely and totally obvious that she has no idea whatsoever what is going on, if that's not a situation that anyone else here is in.
