There's definitely a bit of a delay before the next response. At least it probably meant she was thinking about it?

When I talked with Waver before and thought about it I figured he reminded me of the Doctor.

I still don't think that's wrong, but

If she saw Waver (and Diarmuid) as family, well, she might have to reevaluate how she looked to some other people as well. Most of whom were dead.

Which might go a long way toward explaining how strong her desire to protect those she cared about here was, but it was still a lot to think about.

Not really? Why?
