There are a bunch of hints in Asgardians, like the lies and deception bits and Kid's voice being just a little sinister. And then there's that caption that acknowledges that Kid should not exist. Put those together and it's really clear that this is meant to be part of the larger Kid Loki-Loki story.
Based on that, there are many interesting ways it could go. They're speculation, but they're not unfounded speculation. They're hypotheses. It's not like any of this is coming out of nowhere.
For example, Kid is back. He should not be back, based on the previous story. In fact, it should not be possible for him to be back, as he seemed to have been overwritten and bringing him back would be like recovering files from a hard drive that was first fragmented and then erased. So we know something is up.
We also know that Kid is in the Destroyer. Last time we saw it, your body did not go inside; you piloted it with your spirit/soul. So either the rules of the Destroyer have changed or Kid isn't strictly physical. That's not a guess, that's a pretty much definite either/or, based on the rules of the fictional world. Fictional worlds always have rules and good stories either follow them or break them intentionally. Only bad stories treat the internal logic of the fictional universe without care.
If Kid is not bodily within the Destroyer, that would make it likely that something to do with Ikol/Loki taking his body caused it (or that he's from the Soul Stone) and that a body is his goal. Hence the speculation above. It's not guesses. It's based on the text.
We know that Thor felt very strongly for Kid. So strongly that he nearly killed Loki. He loved that he finally had the brother he always wanted and thought of him as innocent. We know Thor distrusts Loki and is apt to jump to the conclusion that anything suspicious is Loki's doing. Thor isn't going to lock Kid up. For one, when was the last time Thor locked anyone up? For two, we know from previous stories that it's likely that Thor will have one of or a combination of two reactions:
1. He immediately accepts Kid as real and true and still the Kid that he loved from the start. If Kid is not the original Kid in original form -- and as noted above, there's ample evidence that he's either something else or somehow changed -- then this would give good story possibilities for Kid to betray or take advantage of Thor. This would be a way to get Thor and Loki to finally truly reconcile if it makes Thor realize that Loki is more Kid than this new Kid is. Or Thor might think that this is another of Loki's schemes and that Loki is being cruel by corrupting the "innocent" Kid.
2. Thor rejects Kid, knowing that it's impossible or near-impossible that Kid could come back. Most likely, he attacks Loki for this, as even if Thor is sure Kid is a trick or imposter, he'll be unable to actually attack Kid, so he'll hit that default again and accuse Loki. He's likely to think of this as a particularly cruel trick, since Loki knows exactly how Thor felt about Kid.
Now, because of events at the God Quarry and Infinity Stone shenanigans, and the fact that we've been told that AotG comes out of Infinity Wars, combined with SIX YEARS of this story, it seems likely that Loki has something to do with Kid being back. We know that killing/erasing Kid was Loki's big, unforgivable sin, and it's been present in every single story told since it happened, though sometimes in subtle ways. For an example of the subtle bit for that, there is no real story reason for Thori the Hel-Dog to be around -- except to make it clear that this is an extension of the story the gave us both Thori and the unforgivable sin. Thor may have softened toward Loki a little bit, but Thori is there to remind the readers of what happened before without necessarily having to have Thor and Loki stop all the big bombastic netherworld action and talk about it.
This makes it likely that either Loki consciously chose to bring Kid back to attempt to correct the murder he committed or that he happened upon Kid and decided to try to make things right by bringing him "home," maybe giving him the best body he could find as a stopgap -- the Destroyer. Now, whether Kid being off is due to Loki's actions or due to some Pet Sematary-like rule in this case is completely up in the air, since both would make sense with what has already been set up, and each has different story possibilities.
TL;DR: It's true that we don't know what story Bunn is telling just yet, but we know he's placing it as a continuation of the story that started in JIM and therefore can make educated speculation on what the most likely courses might be.
