So a random thought, via the entail of 1377, the house of Lancaster was the next in line to the throne after Richard II. What would happen if Henry if Bolingbroke john of gaunts only legitimate son died in 1386 with no issue? Would John try for another child with Constance of Castile? Would he push for the Beaufort to be legitimised and put in the line of succession?
If gaunt dies as otl in 1399, who might take the bate to remove Richard II assuming he still goes on his tyranny and has no successor of his own body?
