Oh interesting, would there be a suggestion of marriage between Elizabeth and Edward?
Depends on which lords have daughters of marriageable age, I think. Elizabeth already has the taint of bastardy, whether parliament declares her legitimate or not...which I don't think that parliament will do, since it would delegitimize them as a political body, to reverse such an important ruling so quickly. Marrying her would solve the problem of her claim, but then he has no possibility of greater allies, and little to offer against De la Pole. If, on the other hand, his regents pack Elizabeth off to Portugal as planned and one of the mightiest gets the new king as son-in-law, then Warwick is in luck...for now. The nation is still disorganized and tumultuous, and Warwick must pick his way carefully.
But then again, if some powerful lord has a son of marriageable age, he could get the young man and Elizabeth to wed, and claim the kingdom for her. Warwick has a better chance though, in my opinion, although I'm not sure where De la Pole would stand here.
