A spontaneous AU

Alt timeline where instead of giving Starscream his body back, Unicron makes him a sparkling again.
Naturally, he is a little peeved at this but due to being a sparkling again, he's not 100% sure why, at least not until his memories come back that is.

Upon seeing a teeny baby Galvatron goes from "kill" to "love" and takes the baby home, against Cyclonus's warnings, but still. He's their baby now and they're going to raise him with love and care.
