The TVA that Loki went to at the end was NOT the same one he was familiar with, this one is in a branched timeline. So that means that the Mobius that Loki knew is still out there. I'm guessing the 2nd season might show Loki trying to get back to him or something. It all depends on what happens with Doctor Strange 2 and maybe Ant-Man 3. Also, it looks like the rumor about season 2 was correct. What I mean is, the initial rumor said that they were about to start shooting the next season I believe so maybe it comes out right before Ant-Man 3 and leads into that movie?
