Freebird

I don't really know but I came up with the idea when I was listening to Lynyrd Skynyrd's 'Freebird.' It's a combination of Megaman X and Megaman Zero. Iris dies in X4 because of Zero, and from MMZ we know Ciel's got a thing for Zero. Zero might be on his way out of the Resistance base again, and Ciel decides to reach out to stop him, but Zero won't stop because he remembers Iris. Like I said...I don't really know how I came up with this or what it really means.
