What if Kid Loki wasn’t actually Loki, but Thor thought he was and Evil!Loki invaded his mind as Ikol just so he’d have a body to come back in. Sorta like the deal with Sif.
So, what if Kid Loki wasn’t even Loki?
What if he was just some kid off the streets of Paris?
So it was Surrure all this time and not ‘Loki’.
