Now! It is rather baseless speculation time, since I was tempted to do so already and you gave me an excuse
. Sadly, Loki didn't show up in Unworthy Thor, and I rather doubt he's going to in the last issue; however, Aaron's inclusion of Thori, imo, signals another connection to Loki's recent storyline. I'm hoping we at least see their reunion(Loki and Thori--unfortunately, I think Loki's reunion will take at least an issue longer) in the next three issues.
I almost wonder if Aaron pushed his plans back for some reason. Early on, there was a lot of focus on Loki (for it being nominally Thor's title), but lately, he's been rather absent. The more likely case is that he's been waiting for (Thor) Odinson to return, following the end of the Unworthy Thor mini--he might not have planned it all out exactly, and ended up having to put in on hold for a bit. I'm still holding out a small outlier hope that Loki ends up playing a part in Secret Empire--after all, if the Avengers are going to reform, it's practically his
job to make them do so. I did notice that one of the covers had the current version of him, along with Odison (with Jarnborn) on the cover--although, they also included Flatman, so I'm not sure it guarantees him a role of any magnitude. If he does get involved, however, I wouldn't probably expect it until more towards the end, it's not really his bailick.
