Imagine being Loki's past lover. While he's captured by TVA and put into the Time Cell, they don't replay his memory with Sif: they make him watch you die over and over again.
Before Loki could protest or attempt to explain himself, Mobius used his tempad and the hunters pushed him through the just-opened orange portal.
The world around him changed. It was no longer the TVA facility, no, it was something he could recognize even in the most feverish of dreams. Truthfully, he always wished he could just forget that place, push those memories out of existence.
