The plot line was that Loki had escaped after the Avengers movie and was hiding on Earth. He happens to go into a brothel and see Tony there. While he still considers Tony an enemy, he thinks no one should be treat like that. He rescues him and nurses him back to health. Tony becomes attached to Loki and doesn't want to leave him. Eventually, Loki tries to leave Tony and Tony get recaptured by the brothel. ANd that's where the author left it.
If anyone can find it, I would greatly appreciate it!
