Fan theories suggest that Loki faked his death in 'Avengers: Infinity War'

It has been a while since 'Avengers: Infinity War' has released, but fans of the superhero franchise are still not over all the deaths in the film and they are speculating what the next instalment — 'Avengers 4' — has in store. The earlier movie opened with Loki's death, thus shocking everyone, and since then, many have been wondering that he may actually have survived Thanos, the supervillain.
According to fan theories on the internet, Loki hasn't really died, and will return in 'Avengers 4'. One theory suggests that Loki is right-handed and he always holds weapons with his right hand and also the sceptre in the same hand. There have been only two occasions when he has used his left hand. The first was when he faked his own death in the 2013 film, 'Thor: The Dark World', where holds the dagger with his left hand during the entire scene. And the second time when he stabs Thanos in 'Avengers: Infinity War'.
Another fan shares that since Loki has a strong tendency towards self-preservation, his actions at the beginning of 'Avengers: Infinity War' have been out of character. So, the Loki who has been killed by Thanos is perhaps not the real Loki, and maybe just an illusion. Interestingly, if you notice, he looks relatively cleaner than all the other characters on the ship.
What's more, the rumours that Loki will appear in the upcoming Avengers hold water because actor Tom Hiddleston (who plays the character) was spotted on the sets of 'Avengers 4' in full costume.
