I know how much Hermione has wanted to see him again. And Terry's been feeling so cut off from his old friends -- perhaps this would help a bit. I worry he might not want to see her, only because he's still so very guilty over what happened with Carrow. I'm also not sure a surprise would be best.

Once we're very sure she'll be there, I'll let him know, just so he'll have a chance to prepare a little.
