"Got it." Normally Jack wouldn't resist the innuendo he could get out of that, but with someone's child on the line, it's really not the time. He looks back at the Doctor. If his expression doesn't make it obvious enough, it'll be in his mind; I trust you. He gives Owen a little nod to confirm that's he's ready as well.
Missed IM last night because I crashed early, but yes to Jenny jumping in whenever! Jack will likely be quiet for this. I know-- Jack, quiet?!
