Curate, connect, and discover
My theory is that in the blast everyone was sent to their og timeline, but Loki's and Sylvie's time lines had been reseted/deleted so they will be sent wherever and they'll have to search for the TVA agents in their respective time lines. Maybe we'll see Mobius in a Jet Ski and B-15 before they got her bc I feel like nobody talks about B-15 enough.
Edit: Though I have my doubts that they will use the "I don't know you trope again" is possible that the Mobius/B-15 they find is the one before the kidnapped and who kidnapped them was Loki (a popular theory from what ive seen) and would also explain Mobius fixation on Loki variants even if he doesn't remember
