Well, it's mere minutes after Tenant's penultimate episode concluded on Auntie and the three kids next door are IMMENSELY, screaming-at-the sky upset. The expression "It's not fair!" was used more often than a catchphrase in a Moffat script. Mind you, they aren't such uberfans that they understand the concept of regeneration, so the Doctor's "I'm gonna die" is taken absolutely literally...
"He means he's going to regenerate," I tried to explain.
"What's regenerate mean?" they ask, hopeful.
"He's going to change," I said. "Like he did before, with his hand?"
"...he doesn't HAVE the hand any more," they point out impatiently, clearly assuming I'm not the best authority on spoilers about Doctor Who and that I assume the Doctor will cheat those four knocks by growing a clone from a body part to continue the series.
God knows what conversation I'm gonna have when Matt Smith appears.
Interestingly, they didn't quite get the idea that Adelaide blew her brains out. One assumed she'd just died in a domestic accident (fell down some stairs in a dazzling blue flash apparently) while the others actually believed there was some kind of mad squatter in her house that had killed her when she walked through the door.
That's actually far nastier than what genuinely happened, really, isn't it?
