What's your plan for Kuron?
Kuron! The being the fandom has very mixed feelings on my beloved.
The Kuron/Clone arc in the rewrite takes up less time proportionally than it does in the show, for a few reasons! One: me and Lief are under the firm belief Keith would have realized something was wrong with Shiro. Two: a big focus within Cosmic Dust is the team and their relationships. It would almost undercut a good chunk of what we have planned if Shiro just... wasn't Shiro for most of it.
I'd describe our version of Kuron like that post by @\bizarrebazaar13: "what if your doppelgänger wasn't evil it was just a person. what if your doppelgänger wasn't trying to replace you it was just trying to learn to be a person and you were the best model it had. what if your doppelgänger looked at you with your eyes and said with your voice that it just wanted to be loved. what then."
He doesn't know what he's being used for. Kuron doesn't know he's a spy, and he didn't ask to be the first (and only) of thousands to succeed at a perfectly planned escape. He didn't want to "re"unite with his team only to watch who in his heart is his brother leave.
Kuron didn't want to turn on the team, he didn't want to be reduced to a puppet. But his consciousness was never real to begin with, it was a mask for Haggar to hide behind. She even regarded him as such, didn't believe he could have independent thought.
His last conscious action was helping Keith kill this clone body.
