Some thoughts and feels on Lecter Manor Sigil Pic
So Lecter Manor in Lithuania probably does not involve Robert or Murasaki in any capacity. Hannibal is really there at two main points in his life, to my best recollection. When he's just a strange, morbid, kind of child who loves his sister, living a mostly normal life, (after which the family relocates to the woods for safety) and again just after Mischa dies, when he's basically catatonic and it's been taken over to be used as an orphanage, which he now in (heavy handed) irony belongs in. So he gets taken back.
So obviously no Nazis in the rewrite, but Mischa still dies, and as some people pointed out, given the timing and the location, manors were probably not looked upon with too kindly of an eye. With much hypothesis, I would vote he lives there for a while, Mischa either dies off site, or she dies there, but eventually it gets appropriated by the government and one way or another he's an orphaned beggar. There's a little sense to keeping an orphanage at Lecter Manor because it gives Robert an easy way to find him. But like I said, it does kind of seem overly gratuitous to have him be orphaned than put him back in his old home with his mind ripped apart. The angst whore in me is all for that, but you know, she's not very objective.
Judging by the state of the sigil, the overgrowth, the kind of gnarly vines, the fact that it's either Hannibal's or no one else's, unless Robert bought it? But he lives happily in France in the book and doesn't seem overly interested in Lithuania, obviously, no idea how it plays in the show, I would say it's either abandoned or Hannibal bought it, just to have. People have suggested he might have planned to live there, but I don't know...even Hannibal likely wouldn't be audacious enough to hang out in a place WITH HIS NAME ON THE GATE while on the run. Likely, mind you, xD - You never know. And he's certainly going to breadcrumbing to some degree...
So I think it's either, he's come back for a visit, for which I can supply no solid reasoning why he would do that, except for the constant need of his to see the place where the tea cup breaks and consider maybe this time it will come back together again. Hannibal's not stone, certainly not after the events of the finale, whatever he'd like to think, going "home" would probably just put himself in a more vulnerable position, and why would he want that? I would hazard it's a "worst memory" kind of place, for him. But Hannibal does things a lot for the experience of them, negative or positive, so who knows.
Alternatively, it's in his mind palace, which I could see, if we're exploring that, it would make sense those gates are somewhere in his mind.
Or, Will is there, which to me, at present, makes the most sense. Will is chasing after his history, this is an obvious place to go. (See: Hannibal's name on the front door.) And I would die to have Will empath on child Hannibal. DIE A LOT OF DEATHS.
Anyway, just some odds and ends.
