Okay between gardening and walkies, I did have a suggestion!

If Alucard's tapped by say, Thancred, to help out with this situation, Alucard could use his blood to bait Himeka into attacking him specifically. His blood has healing properties (and a few weirder side effects, would Himeka like to float?), and if someone can open a portal to get them to the ocean, perhaps that could at least shock her back out of the immediate present?
