1) Loki was put into slavery as punishment, and was treated horribly, but ends up being given to Tony with his young daughter, whom i beleive to be Hela, and i thunk she was born because of rape. Loki begs Tony not to hurt her and Tony tries to get them to realise hes not going to treat them as slaves. Eventual frostiron i beleive.
2) There's another with the slavery thing, but Loki was brought to tony because he claimed that he was pregnant with tonys child, in order to protect the unborn baby. Tony plays along and again tries to help Loki. I think that loki ended up having twins and then suffered major postpartum depression because he had thought that after the babies were born he wouldnt be allowed to keep them. All Loki had cared about was keeping them safe until they were born and knowing Tony would then keep them safe.
3) Tony and Loki are together and Loki is suffering from postpartum depression. He hates himself for being jealous of the time tony spends with the baby. He goes for a walk with the baby and gives it jelly beans (?) To make it stop crying and then is convinced he accidentally killed the kid. He tells tony the kids dead and tony rushes home to find the alive kid in the stroller and lays into Loki, but Loki starts/was having a mental breakdown and tony realises what he was suffering from and tells him its okay.
I hope someone knows these fics. I really loved them. Thanks in advance!
