A lot of stuff happened in The Mighty Thor #8. A lot of confusing stuff. The mysterious Tanarus has seemingly replaced Thor as the God of Thunder in everyone's memories, and it seems Loki is the only one who remembers that things were once different.
In the next issue, Loki turns to Donald Blake for help, while the All-Mothers go to war against a new enemy.
