Oh yeah, her too, though she probably realizes that having it herself would be quite risky for her. The other woman who won't be happy at all should be pretty predictable ;)
Yeah, Eleanor likely would be pissed that her husband is giving a duchy to his son born from another woman after they were married
Would Henry be as eager to hand out quasi-royal dukedoms (Clarence, Bedford etc.) to bastards in a scenario where he has legitimate sons?
