This will no doubt have to wait until all the episodes have been broadcast, but if Jenna-Louise Coleman's character doesn't make it to the end of the latest Titanic I shall be surprised if there isn't a flurry of fixits where she gets saved by one or more Doctors. Or the Dream Lord, of course.

Presumably, if Ten's involved, he declares he's the Time Lord Victorious and he's going to stop the ship sinking in the first place, and don't think he won't just because Nine and Seven have already seen it go down! Time can be rewritten! Just you watch him!! Count the exclamation marks!!!
