Sibling love is awesome! I feel like I want to understand Gwen's personality better! I want to know more!!
I think for Gawrgaru, I've been increasingly moving in the direction that he's extremely softhearted (despite his size/muscles), driven mostly by family expectations (he does pretty much everything he's told to do), but generally not talented with very much except muscles. In other words, pretty bad at school, a little dumb, and also extremely gullible with a soft spot for cute things. Has difficulty with saying "no", struggles with expressing what he wants since he's always trying to please his father/family/etc.
In other words, he's a himbo!
Make senses! I can picture it!

Works with my headcanon too!
