[So, guess what. She's missed all that carnage around Christmas. She spent the entire day in the world of the fireplace with the
phantom of her Doctor, just for the chance that he--and the world she saw--might have been real. On the off chance, were it real, she could offer some comfort being there even if he didn't consciously know she was. She only returned when she coul physically no longer bear watching any longer.
She's ignored the constant phone calls since, first in an effort to reign herself in, then because she's too busy planning ways out of the city.
In the end, she's decided there's nothing she can really plan until she knows what happens if she just tries to walk out.
So that's exactly what she's doing. Walking down Mayfield's streets, looking for a direct way out.]
