Ha, guess I could have just requoted you Doctor
Some spoiler space....

















I may have missed it but couldn't the Face of Boe done his thing years before without the cost? How hard could of it been to open up some doors? (granted, really huge doors but still)

So I'm going to guess Boe's message to the Doctor means we'll be seeing Romana again! I realize the popular guess is the Master & I'm sure we'll be seeing him again but it would be a nice surprise to see a friendly face survive. She was in e-space after all.

Fair play!
