Chloe blinks a little at her voicemail, shaking her head in confusion. She's gotten to the point where she can recognize Krycek's voice, and...surely something must be wrong with him. That's the only plausible explanation for that message. Grabbing her phone quickly, she calls him back, and leaves a message for Jake too.

Then she listens to Lee's message, and it occurs to her that perhaps there's a larger problem on campus. Or maybe everyone got bitten by gremlins except for her. But just for courtesy's sake, she returns the call.

ETA: When Chloe comes back later, she finds a very TMI message from Parker. At least she knows this one went to the wrong place, and she leaves Parker a message to let her know.

Chloe barely even gets through the second message about her supposedly missing bra before she hits the call button and returns Crichton's call.
