Oh man, let me tell you... Midna comes from a bit of a fragile canon point, Zelda pretty much just saved her life. So because of that... I would really really love if there was an opportunity in the future for Midna to sacrifice herself to save Zelda's life!

I'm not sure if there will be a chance in the upcoming plot, but it's definitely something I would love to have the opportunity to play out, and I imagine it would definitely bring them closer to some semblance of friends! Or at least... as close as Midna comes to that sort of thing, lol.
