I may have to come back to this later.

My first question is that now that we know Loki will be helping to hunt "bad" Loki... is this another variant or is it this version of Loki (I'll call him Loki prime) later in the show after a turn to bad?

We know the "bad" Loki knows about the TVA and their reset bombs. Since he sets traps for them and has been taking them. Loki Prime has yet to see the bombs, I believe.

Loki had a whole range of emotions seeing how his past played out and how his future was supposed to play out. True grief for his mother. Some love / sentimentality for Thor.. it was like the sort of redeemed Loki we see in ragnarok.... then he sees Thanos kill him. That totally took him to a different place. All the warmth was gone and I think he was now seeing a new plan. The power of the TVA, infinity stones as paper weights. He can make Thanos his puppet. I think he plays along and then is on the run and turns heal by the end, sets off a.bomb at the TVA and unleashes the multiverse of madness.

He still craves power at the end of the day. He is always trying to work the angles to keep an advantage. But he knows that now is not the time to fight it.
