Wait, that was a Noble Phantasm? I thought that was just magic, which is why Saber was trying to stop it, preventing someone from using a Noble Phantasm just because they couldn't talk would be ridiculous.
You're going to need to clarify where I'm autohitting, because I don't see it. I only said that Saber was aiming for Caster's throat, I never said he'd already hit her or anything like that. I expected her to dodge or block, the maneuver's only purpose was to disrupt the spell she was trying to cast on Alysis.
As for William, I don't see anywhere where it says that he actually blocked with Gram; to me it sounded like he was just standing there and allowing it to hit him, while making a lighting rod with Gram in hope that once it had struck him it would be channeled out of his body. Since I'd explicitly said that once the lightning struck him it wouldn't leave his body, that would not have worked.
If you're still seeing something I don't then I'll correct it.
I'm not actually sure. I was half awake when I typed that up, so feel free to veto it. I mean, Alysis is a first year student, there's got to be some times when she overestimates her magic. :maybe
