thinking about how loki needed to rush out towards the gangway like that and shut the door on sylvie and mobius before saying his goodbye.
mobius wouldn't have let him go. he would have grabbed onto him like he always did – the way he always held onto loki for as long as he could, longer than anyone else would.
and he wouldn't have let loki go.
and in their final scene in the interrogation room we saw loki literally holding mobius' hand until the man dissolved in front of him.
loki wouldn't have let go either. that's why he needed to run out like that and shut the door on him. that's why he couldn't give him more of a goodbye. neither of them would have been able to let go.
i also think this is the same reason loki chooses not to freeze time in that final moment with his friends for a longer last look (because we know he's learned how to freeze time).
but he knows he may never unfreeze it if he does. and he has to do this before he can change his mind.
the one time he most wants to be selfish. and he can't.
