Oh, and now that we know it's going to be a thing, I think Raye's probably right, and it's most likely hammer which arrives in the last issue. Having someone become worthy isn't something you do in the middle of the event, imo. Especially not since things are looking bleak, according to the solicit.
So, I guess that leaves us with a couple questions: How is Loki going to come back, and how is he going to earn Mjolnir? I already thought that his death was a plot of his. That's like...a thing for him now, I'm pretty sure. Question is how he's going to undo it, because I think he is actually dead. The new series makes it look like there might be some type of time reset, so maybe that could do it(though I'm skeptical of time resets). I kind of wonder if he has the time stone, because that mini isn't finished yet and it would make some sense if he ended up with it (future knowledge stuff, especially). If he does, I hope it's more difficult than just a time reversal (though you might have to go all the way back to Malekith's childhood and mess with that to prevent the war--at the least, if there is time resetting, I hope it's one of those cases where Loki's tried resets and every last one of them up till now has failed).
Not sure about Mjolnir yet, I'm hoping for a heroic last stand, on the verge of death kind of thing.
