8 Possible Thor Ragnarok Post Credit Scenes We'd Love To See
3. Loki's Deception
Loki is the unquestioned God of Mischief, and both Thor and The Dark World ended with the deception of his older brother (and the whole of Asgard in the case of The Dark World).
This has always been important to Loki's character, as the audience can never be certain of which side he is fighting for. This adds a completely different element into the movies, as we don't know if we can trust Loki, and more importantly, neither do the other characters.
This should be no different for Infinity War. Loki is a wild card and will make whichever side he is fighting for considerably stronger, but it just wouldn't be Loki if we didn't know which side that was.
If, when Thor: Ragnarok comes to a close, Loki is on Thor's side, we may see him switch allegiance after the credits. Yet, knowing what we know about Loki, and how his character has been built up over the last six years, in no way would this swap be necessarily permanent. Could it be a double, or even triple bluff? This is the magic of Loki, and the uncertainty around him only increases the stakes for our heroes even more.
