In this feature, I spotlight storylines that have been, well, left unresolved. Click here for an archive of all storylines featured so far.
This week, we take a look at the infamous favor that Loki still owes Spider-Man apparently!
In Amazing Spider-Man #503 (by J. Michael Straczynski, Fiona Avery, John Romita Jr. and Scott Hanna), Spider-Man runs afoul of a powerful being known as Morwen, who has possessed a young woman. At the end, Spider-Man encounters Loki, who is searching for Morwen, as well....
They take down Morwen, as Spidey discovers that Loki is invested because the young woman who was possessed was Loki's daughter (she doesn't know that she is Loki's daughter).
In the end, they save her and Loki then says he owes him a favor...
Spidey makes sure to check on the safety of the daughter, which I always thought was nice...
And that's it. It never came up again. I believe during One More Day, Loki was "dead," so that was why he didn't go to Loki then, but it's weird that it's never come up again. Dan Slott once hilariously pointed out in response to a fan question on Twitter that oh yeah, Spider-Man took Loki up on the favor off-panel one time and Loki helped him move a couch.
Okay, that's it for this installment! If you have a suggestion for a notable unresolved comic book plot, drop me a line at brianc@cbr.com
