I do! Valka has so much life and energy and youth and, I mean this completely non-offensively, it’s likely because she was no longer a mother. I mean, clearly she’s a mother, but there’s a certain stress that she didn’t carry around, not like Stoick did—the stress of constantly revolving around another human life. Yes, she was burdened by her choices and her past, but she also got to explore her personal desires at her whim as soon as she let go of her human ties. I can see her spending her years nurturing dragons as well as being nurtured.
I went on that mini-tangent for a reason. Games. Games and competitiveness and wanting to impress her son. Valka joins in and she gets to show off. And while Stoick was brazen and boasting and all that, I don’t think he could fall captive to showing off quite like his son or his wife could (which may stem from being an underdog at some point in their lives).
So yeah, I can see Valka observing a few games and then deciding "yes, I can beat these punks at their own game". And, hey, maybe there’s a tiny bit of anger behind that competitiveness. Injustice at the thought that this is what happened to Berk without her. So she wants to show them. She wants to show them what a real dragon rider is capable of.
I think the idea that “oh no using dragons for entertainment!” would only be split before she saw how much the dragons enjoyed it as well. They aren’t being abused or forced, and so long as it’s symbiotic, Valka won’t go all feral dragon lady on anyone’s ass (though I do like the idea of that antagonist/dangerous Valka canonically cropping up every now and then as she tries to integrate into Berk).
Woah, it just occurred to me that you wrote this to my personal and not my fandom…. WHAT ARE YOU DOING YOU’RE MESSING UP THE SYSTEM
