Continuity....
Pffffffffhahahaha!
"Everything in creation is flawed. Humans don't need to be mentioned. Air, intent, and even time. My eyes can see the death of things. They're special, like yours. So I can kill anything that lives. Even if that thing is God."

Hmmm, we know that Schrödinger can enter imaginary worlds as he pleases, so he could enter UBW if he wishes.
The question is, can he take things with him when he leaves? The fact that he is clothed when he teleports would seem to indicate that he could, but...
Yes, I thought that was it. And being everywhere and nowhere at the same time, it means that even if you kill him somewhere, he's still alive somewhere else, therefort, not dead.
Which makes up the jig of his now I'm here, now I'm not and ressurection tricks. Nothing about him invading people's minds/souls though.
He demonstrates the ability to be in imaginary locations in the Seras vs Zorin/Doc fight. Specifically, while Zorin is dying and looking through Seras memories, he appears in that imaginary space.
Right at the end, when Zorin is defeated, Schrodinger appears in his visions of Seras' mind. And gives him a message as he dies.
Zorin is a she.

I want a crack fight....The true reason why Walter defected to the Nazis and gain a younger body wasn't to fight alucard but to compete with Shirou in terms of...butlerness?
His old bones won't do against the youthful energy of his competitor thus using a younger body to show how a true 'young' gentleman fights.
Teasing the Penguin God!
Regarding Helsing and confused genders, it took me most of the series before I even realised that Schrodinger was actually male.
Spoiler:
That was pretty much my reaction. It took about a dozen instances of people referring to Schrodinger as "him" and "he" that I figured that it simply couldn't be a typo.
