The mouse goes quite unnoticed since both Starfleet officers are busy with their paperwork. The girl's scream, however, does not.

Chekov jumps to his feet, sending his borrowed datapad clattering to the hard floor in the process. It's a bit of an overreaction, but in his defense, he has been having a very strange evening and his nerves are somewhat frayed. When it becomes clear that nothing terrible is happening, he sheepishly retrieves the pad and sits back down. As much as he would like to try talking to the girl again, he's quite aware that Chapel is better equipped to deal with this than he is. He'd already made her faint once, after all.

Chapel sets her own report aside (calmly -- it takes more than a little screaming to surprise her) and approaches the girl. The mouse gets a small frown, but as it seems to be with their guest, she doesn't make a move to escort it out. "Hello to you too," she says evenly, as if oh bloody hell is what all patients say when they wake up in medbay. "There's no need to be alarmed," Chapel continues, shooting a glance at Chekov since he apparently needs to hear that as well. "This is a medical facility. You're safe here."
