Sure, but you’re still ignoring the fact that he outright says his mission is to bring his family together? He tells it to the staff. Also if you walk around in present time as him, interacting with everything you can, he also talks like Loki.
Fair enough, they don’t have a reason to kill him maybe, but they surely do not have a good reason tot tell him who the leader of the assassins is right now. That is like, what, one of their most valued secrets? And they just tell it to a random stranger who just came out of a machine that kept him in another realm for a few thousand years. He got it all a little too easy.
I dunno. Either way, it’s a hefty spin. Very curious what the next game will bring.
