Let’s think about our Mobius’ POV of that last moment.
He’s running through the TVA, in search of Loki until he spots a familiar black mop of hair and relieved, goes in for a hug but is stopped by a forcefull push and a “how dare you lay your hands on me mortal”. And Mobius is confused for a second thinking maybe he crossed a boundary, maybe they’re not at that stage of the friendship yet where he gets to initiate any form of contact.
So he starts to apologise “I’m sorry Loki i thought we..” until he takes a good look at the demigod standing in front of him and realisation hits him “wait....you’re not my Loki”
