Loki... Is he really dead?

Tom Hiddleston went to the Late Show and told two important things about the series. First, we will know what happened with the Loki who took the Teseract. Second, we will really know if the Loki from 2018 is dead. WAIT WHAT?!?!?

Isn't he already dead?, the Russo Brothers confirm his death many times, but Tom has changed everything...

So, what could happen in the series to explain Loki's death (or not death)? 

Firstable, we must know how Loki from 2012 can travel into time with the Space Stone, there could be a simple answer: The Tesseract can take you where you want, so you can go to the Quantum Realm and leave it at any moment (it could be like the "Time Heist" in Avengers: EndGame). Could it work? maybe. So, Loki with the Teseract will be travelling in our history changing everything (we don't know if it's our timeline or a new one).

Why is it important to determinate Loki's death?, very easy, because now we can create two new theories.

Before I explain the theories, I just want to say I think he's really dead, so I must look back and seek my old theories about Loki before watching "Endgame" (it's cool to use them again), I made some wonderful stories about Loki coming back to life. 

I always thought that Loki was dead, but asgardians don't die forever, I mean, some of them go to Valhalla and the others to Helheim. In my theories I supposed Loki went to Valhalla because he died like a hero, before Endgame I thought Thor would have gone to Valhalla rescue his brother, that didn't happen, but now maybe is Loki from 2012 who can rescue Loki from 2018. Why not?, maybe this Loki with the Teseract want to travel to 2023 and figures out that his version of that time is dead: so he goes to Valhalla and helps him to escape, but that Loki (2012) is still bad and he wants to make mischieves, something that Loki (2018) won't allow. Loki from 2018 fight againts the other one, takes the Space Stone  and sends him to his real time to fix the new timeline.
This could be an option to bring Loki to life in the series and to have him back in "Thor: Love & Thunder".

It would be awesome to have back this Loki, he's the real one and his relatioship with Thor was at the best point. But... maybe there is another chance to get that Loki again...

This theory is new, I never thought about it, even when I knew the series will be about the past, so I don't support it a lot, but it could happen.
Do you remember when Thanos was killing Loki? at that moment we saw some strange things in the background, some said that was Loki with his helmet. I never trully believe it, but now it could make sense.

The Loki from 2012 travelled to 2018, just in the moment of Loki's death. When the ship exploded, he took Loki's body and saved him; he wasn't really dead. He took him as a prisoner and till 2023 (or maybe more), Loki from 2018 couldn't escape. umm... a little weird, isn't it?

But... one more thing, when Loki was about to give the Space Stone to Thanos, after saying to Thor " I promisse you brother, the sun will shine on us again", thing may not be real, I mean. After that, Loki disappeared from the battle and reappear when everything was done, Was he really Loki from 2018?...Maybe it was Loki from 2012, they could have had some adventures and made a bargain between them, so that Loki would have died. Meanwhile, Loki from 2018 escaped, he was trying to find out how to kill Thanos but he wiped out with the snap and didin't come back till Hulk's snap. That how Loki could be alive.

Which theory is more possible?

It would be great to read yours... but we will have to wait till 2021 to know the truth.

Meanwhile... Enjoy!
