Crap, would've preferred our positions were reversed. Oh well, hopefully this will at least throw Meira off a bit, if only for one pass.
> Have our human half and ghost half start running forward and angled slightly away from the horse's path (ghost half angled a bit to the left, human half angled a bit to the right), with both halves taking a two-handed grip on their respective swords while running. Don't turn too far away from the horse's path, as we want to keep both halves in slashing range of Meira, but our two halves should separate enough that the horse could run between them without trampling either of them.
