Which is fine because this is a different Loki on a different life path. He would be on a branching timeline if he’d not been captured by the TVA.In the first series the writers had to make the most of a bad hand. Loki had received significant character growth over the years, especially by the end of Thor Ragnarok, so that was the character most viewers would want to continue following. But the Loki that was available was the half-insane megolamaniac from the end of Avengers. So they basically had to fast-track his character growth, which certainly didn't feel as organic.
I don't think the result is unrecognisable, but he's still not quite the Loki he was when he sacrificed himself at the start of Infinity War.
