"Gallifrey," she'll repeat slowly to herself, hoping to keep the name close in mind. All she could do was remain close to the Doctor. Accepting whatever kindness he's willing to offer. Her head will remain on his chest and her breathing will improve as he begins to pat her back.

She'll continue to observe him. It was clear from his deep expression he didn't believe her. He believes otherwise. Most likely believing he should have died alongside them, usual signs of survival's guilt. A feeling she knew all too well. Only issue was -- she wasn't very good at comforting others. How can she help him?

Without thinking it twice, she'll end up returning his hugs by taking hold of him in return. Bringing him close enough to wrap her arms around his shoulders. This was all she could do is mirror his kindness.
