Say by some chance Edward V, the young 17th Earl of Warwick and Edward of Middleham survive to adulthood and have families of their own, might we see a Cousins' War 2.0 due to their rivalries (esp. Warwick and Middleham's due to their shared Neville inheritance)? After all, the three sons of York fell to bickering and squabbling amongst themselves (particularly Clarence vs. EIV and RicIII) almost as soon as the crown was in their family - a case of falling out amongst thieves.
What might the future hold for the three Edwards?
