Ed had been out for a walk to make himself get some fresh air and enjoy the snow while he's still not sick of it yet. Now he's definitely ready to go back inside and get warm.

He sees Charlie as he approaches the steps to get back in and is pretty sure he recognizes her. "Isn't it a bit cold to be sitting there?"

Time to find out if she recognizes him. If so, she's just been quiet for awhile. If not, he gets to go through explaining the place to her. Again.
