thats a good question...do the deleted scenes reveal anything? i havent seen them.
she wasnt at the fire when jim said it, and karen never said anything at the fire or to anyone other than jim...
once again, that icon is priceless!! haha that face!

Deleted scenes don't say anything. So I guess she doesn't know. I don't think anyone knows that Karen is.

oh, maybe you were thinking that Pam let her feelings out because she thought Karen might be leaving? that would be interesting...
