What convinced Lucian wasn't, ultimately, that Lianelle couldn't remember her past. Sure, it was suspicious how all of her connections to anyone besides May had been cut or weakened, but that was only enough to push Lianelle so far. What convinced him that May was mind controlling his friend was Lianelle's lack of interest in being anywhere but by May's side. Lianelle didn't do that for anyone. She loved Katia with an intensity Lucian had hardly seen in any marriage, but she'd only visit Quiteria for a week at a time - never staying unless it was urgently required. When armies had been raised to fight the Magyar Lianelle had been there, but even then she'd ride off alone often, returning with news about how one village or another was now free. Seeing her relegated to a bodyguard and lover of someone she'd just met, with no apparent intention to ever leave, was... wrong. It wasn't Lianelle.
And so, this is how Lucian finds himself digging a hole in an unremarkable forest in west Austria. Well, digging several holes - the landscape's changed enough in the last 1200 years that it's difficult to locate the exact spot where he and his men, victorious but weary, buried the Magyar's artifacts that they could not understand the purpose of.

"Oh, and this will be even more efficient if the other esper world has another alternate of me."
"In that case, you'd find me in Toronto under the name Lifeline - assuming everything went exactly the same. If there isn't an alternate Haru, or I didn't get attacked by a mysterious creature a century ago, it would be different. Though in either case googling my name, Lucien Sulzberger, would work to check if I was even born there."
"But if the first name's all I can expect will surely match it's kinda needle in a haystack and anyway if he's an esper his name might well not be public."
"Possibly the useful thing would be to search for is my power, since that's what we want regardless."
"But of course then we'd miss any of you who haven't awakened yet. Or who have different but also useful powers, the way he does," gesturing at Isabella's Lucien. "- hey, May, just out of curiosity -" He holds out a fist.
She reaches in his direction. "Well, with at least one of you I'm -" She makes contact with Haru.
