I was at a BL event in Dublin 4 years ago at which ADB and John Ffrench pretty much admitted the Scouring would be done. Ffrench in particular said he wanted to explore what Dorn and the IFs do in the wake of the HH.
I hope french doesnt pussy out of making the IF look like a bunch of bitches in the Iron Cage (if they write about that, which they should). He has a few IW books under his belt and I always feel like he hates them somehow. No matter who they face, they always look a bit weak - even when theyre doing a siege, which is sort of their thing.
