Re: SUPER UBER SPOILERMANIA: The Ending... What Does It Mean?
I don't know how up people are with their comics but what happens with Loki reminded me of what happens to Doctor Doom in the Fantastic Four.
Basically the Silver Surfer and Terrex (herald of Galactus) fight and crash into a immobilised Doctor Doom seemingly killing him, at the same time of Doom's 'death' a bystander gets angry and storms off (actually he shoves Aunt May). Turns out Doom at the moment of death transfers his consciousness into the bystander.
In the movie it looks like Loki does the same thing.
