Loki, helping Thor out

[seranita.livejournal.com]

I was wondering whether anyone has fic recommendations where Thor has managed (be it through his fault or not) to land in a situation detrimental to himself/Asgard/Midgard and Loki comes to help him out. Maybe Thor knows about it, maybe Loki keeps his intent concealed from him (because he can't have Thor knowing that he does still have affection for him, no way). Can be pre- or postmovie. I'm actually not looking for classical rescue/healing-situations, but more like... political stuff, blackmail, Thor lost this really important artefact, things like that.

Thank you in advance!
