The best way for Martha to keep her mind off of everything that's happened both to her and to others is by making certain that she stays busy. Someone definitely cleaned up this place in her absence, the Doctor had even told her as much, but she doesn't know the details beyond that.

Even so, she's been changing the sheets on the bed, organizing supplies, and checking in with the patients who she has, such as Sam, though at the moment he's passed out due to all the pain medication.

So it takes her a moment to realize that there's someone there, though eventually her senses pick up on it, sending a spike of fear up her spine until she turns around and finds Daryl.

You're back.

"... So you heard? I suppose news travels fast." Martha moves toward Daryl, pushing up on tiptoes to peer over his shoulder as she can't quite curb her paranoia right now. "Are you all right? Been staying safe?"
