I am delighted to announce that the Jonathan/Elias fics are exactly as unhinged and wonderful as I could have hoped.
However! they come in three basic flavours:
1. Elias is a bastard and Jon suffers
2. Elias is a bastard but he’s inexplicably soft on Jon
3. Elias is a bastard but Jon is into it.
And I have yet to decide which one is my favourite :D
