Okay, I had another thought about the whole Avengers thing today. Yeah, this is all just a hypothetical, and it may not happen, but I think it fits together.
So in Aaron's Avengers, when they bring in the Russian team, they have Perun and Chernobog with them, it's obviously meant to parallel Thor and Loki. When he sees this, Tony says you 'never go double god' and he's proven right when Perun and Chernobog end up fighting each other rather than anyone else, and it screws everything up, and he's like 'see?!' So. here's my thought about how that could play out as foreshadowing, even though it's not going to be Aaron doing half of it, admittedly this likely would have made more sense if he was still writing Thor, but Cates still may be working towards Aaron's plans in this regard.
It's looking like Thor and Loki may fight (unfortunately ) but this time Thor may be the aggressor. But regardless of who starts it, what if they end up on Earth, and the Avengers show up to try and resolve this situation, and they end up taking sides. While I am not too interested in another Civil War, i think you could spin this as more like them trying to prevent one from happening, by keeping Thor and Loki separated, and with Tony arguing against going 'double god' by splitting into two teams. Like, the team ends up split, but other than Thor and Loki themselves, everyone is actually in agreement that it's for the best, even if their sympathies may lay more with one or the other, it could be the catalyst for a second team. I could see Tony siding with Loki after events in Loki's solo, for instance, or at least feel responsible for him because it was him that made the deal with Loki, so Tony, Loki and some others do one team, while Cap and whoever take Thor on the other side, expand both with a couple new members, and done. Maybe T'challa acts as a neutral go between between everyone. This also depends on Thor being back with the Avengers, but based on some of Cates' comments (he said some of his time with the Avengers may be shown in his Thor run) and some preview art for some upcoming stuff does seem to suggest he will be, despite the 'retirement' not Tony gave him, i guess that was only temporary.
The catch here though is that prior to this, or maybe during the confrontation, Loki would have to do something to demonstrate that he is Avengers material. Tony already laid out his requirements: pick up Mjolnir. While I think he said it while expecting it would never happen, a deal is a deal. I don't think Loki could right this instant, he's come a long way but... he's still a ways off. Though the 'worthyness' requirements Aaron laid out at the end of WotR, do seem to fit Loki rather well, actually. But I could maybe see something happening during the fight, especially if it IS Thor that is attacking him rather than the other way around.
I think with the recent tease about the hammer getting heavier for Thor, Loki picking up Mjolnir (again, technically) may finally happen. What i am having trouble deciding is, if the Loki hero moment, whether it is Mjolnir or something else, happens before Thor and Loki end up fighting on earth, or like AS it's happening. like, would Thor be mad that Loki 'stole' Mjolnir and that is WHY he is attacking him, or is he attacking him for another reason, and during the fight something happens that causes the Avengers to choose sides? Either way though, I think now that Thor would be pissed off. I didn't before, during Loki's solo, I was kinda thinking he'd maybe be ok with it. But now? not so much. I think, with his recent attitude shift, he would see it in the worst light. It would be like being shown to be the bad guy in this situation, and no one likes that, and he also still places a great deal of his self worth in being able to lift that hammer, so losing that, again, so soon after being unworthy recently, would sting. But also from a political standpoint, it's not a good look for the king to lose the symbol of his power to a rival king. It could make Thor look weak, or at least he'd think it made him look weak, given how he was portrayed in the first issue of Cates run, and he may feel the need to re-assert his power. I think this is a large part of what prompted Odin's aggressive response to Jane. Which is why I am having a hard time deciding if it would happen before or after the Avengers moment. Before would give Thor more justification (in his eyes, anyway) to attack Loki and Jotunheim, and Loki could still be all like 'here i am with the hammer, deal's a deal' to Tony and then Tony is like 'can't go double god' so split the team to keep the peace. But during may be more dramatic, and give the Avengers more reason to give Loki a chance. Either way though, I am kinda picturing Thor hucking it at Loki again, but this time Loki picks it up after maybe being knocked to the ground by it. very dramatic. But I still feel he would need to do something before that to demonstrate why he can lift it.
Either way though, I hope eventually they can reconcile.
