Lenalee has recurring dreams about the destruction of the Order that apparently Allen Walker once shared isnt it? Now whats the meaning of them sharing thesame dream?

I think that maybe The corazón is actually división, split in two and Allen has one half while Lenalee has the other half. I'm probably wrong but thats what I think. P.S It would be better if Allen had the corazón because he is awesome but that wouldn't connect him with lenalee.
