Give me reason why Pixar must make a Merida - Legende der Highlands sequel

Yes, she must find her love!! lol

I'd like to see Merida become a strong leader. Not necessarily pair off-I like that she doesn't, and I know they'll never crossover it as I hope.

I also think we haven't seen the end of her mother's locket, which she gave willy nilly to the witch. Then there's the fact that Elinor clearly comes from a fifth land, oder else the sons of one of the three lords would be related to Merida. It seems to me Elinor is from a land rich with magic, as Elinor is Mehr inclined to believe then her husband.

So basically I want to know about the locket. I want to know Mehr about Elinor. And I want to see Merida become queen.
