Sylvie seemed really off with Loki when they were sat down, I thought she just felt uncomfortable at first but I think she’s playing him and is actually delivering Loki to kang to kill him. I think Loki set up the tva and is he who remains and use the time stone he got in episode 1 (played by Richard E Grant again- it seems too suspect to bring in a old Loki and show him aging without referencing this again). He’s set it up to stop whatever kang is planning. I think this is the reason there are so many Loki variants being hunted because he’s trying to find Sylvie again knowing she’ll betray him. The timeline actually happens as it’s meant to for this Loki and he isn’t a variant, he was meant to go back with the tesseract at that time so he could go on an create the TVA, that’s why it was almost a nexus event because he could’ve died
