Another Walker Up;date

I got to Atria and found her sitting in the walker out in front of her apartment.  I think she might have locked herself out and since the walker was there in the hall, she sat in it.  I didn't comment on it and just opened the door and we went in.  When we left, she opened the door, saw the  walker and asked if it was mine.  I didn't make a big deal out of it, just said that she had been sitting in it earlier and that it belonged to Atria.  She said nothing.
