What in the name of Athena daughter of Metis daughter of Tethys daughter of Gaia the self-created are you talking about?
“Time can be rewritten.” The Doctor changes history all the time. There are certain fixed point that CAN’T be changed, but those are not the majority. It’s changing one’s person timeline that’s the bother (which admittedly means Lecter’s request will fail.
If he even gets to make it. Nine, Ten, Eleven, and Twelve will all see Lecter for what he is immediately, and Twelve, I think, is pragmatic enough to off him.
Lecter is not easily offed. Never watched the show, but my daughter is a great fan and tells me about it. I’ll go a step further and say that Lecter is even less easily offed by whimsical goofballs from universes aimed mostly at kids.
Anywhere, here’s how I see it. Lecter meets the fairly-odd & rude Twelve; disbelieves his claim of being a time-travelling alien; murders him for having bad manners; and, while preparing to butcher him, is forcibly and lethally shown that, while the Doctor is certainly a madman, he is not a delusional madman.
Okay…if you say so. As I noted, I have no direct experience with the show and I am going on what my 14 year old daughter (an obsessive fan) tells me about it. It sounds like it is about on a maturity level with the original Star Trek series. Lecter, in the canonical works (Red Dragon, Silence of the Lambs, Hannibal) is not easily offed, but he isn’t prepared to deal with time traveling opponents.
Man, that would be hilarious. House spends the whole episode mis-diagnosing illnesses that could cause delusions, while the Doctor relies on his immortality to barely survive the side effects of the attempted treatments. Meanwhile, there is witty banter regarding why the Doctor calls himself the Doctor when he does not appear to be a doctor of any sort.
Dwight Schrute: I knew it! I knew time travel was possible, but everybody laughed at me. WELL WHO’S LAUGHING NOW? I have a list of 1,238 historical events we must change in order to prevent the inevitable robot invasion.
Jim Halpert: I hacked Dwight’s list and changed them all to the birthdays of his ancestors.
Creed Batton: They found me! (Escapes through air duct)
Kevin Malone: What’s this button do? (reality disintegrates)
Gilligan would manage to trip and spill coconut milk into a critical panel on the Tardis, trapping himself and the Doctor on an uncharted desert isle, and thereafter hilariously thwarting all attempts at escape or rescue.
Granny Clampett would prolly do another hit of “rheumatism medicine” then make The Doctor some vittles while explaining that she’s a Doctor, too…until he tried to make Ellie Mae a companion, in which case she’d cut a switch…
