I had this idea once of Amy having a misadventure, winding up in Blaze's dimension, falling in love with her before she could find her way back home and being all confused that suddenly Sonic isn't the only one big love in her life. Another idea I didn't have the organization skills /time to realize, but here's one moment at least. :p
Blaze shares some traits with Sonic, but her personality is also different in ways that make me curious what kind of chemistry they could have. (They're also just really cute together for some reason. :D)

EDIT: (I feel compelled to point out that this is a very bad way to carry somebody – I confess I draw it because I like how it looks /the emotional associations. In reality you should never, ever carry an injured person this way unless you have no other choice. It works on a small child, where you can properly support their neck and back, but not on someone closer to your own size.) /EDIT
