Very true.
I feel like though you are giving a little too much credit to Conisburgh, and not enough to Bollingbrooke, but at the same time why would you give credit to Bollingbrooke and the Lancastrians
.
On a serious note fair point, but that does to be scraping the barrell a little bit. Henry had no quarrel with Conisburgh and has no reason to anger him or Norwich directly by taking land that Norwich would set aside for Conisburgh, so I'm going to be more cynical and say that Norwich purposefully did not want Conisburgh to have land or much power.
She may have done the crazy stuff after Langley died, but she would still have been seen as an enemy/potential threat before that being married to Thomas Despencer who attempted to overthrow Bollingbrooke.
Also how has this managed to turn into a Conisburgh thread
