What does Champ think of his mom? As in, how she acts? Also, has Champ ever met Vex? Does he even know she exists/how she is?
Good question! I think Champ loves his mom, as most kids do. He is her child, and I think despite his age, he will always kind of see Jewel from a child's perspective. Her flaws are not as pronounced to him, he assumes she knows best because she is his elder.
Yeah she might be a bit of a Karen, to put it lightly...but Champ still looks to her for guidance and love, and she provides those things the best way she knows how. He sees her doing her fussy Karen thing and assumes she must have good reasons for it, because in his mind she is older and wiser than him.
Tekeetian culture places heavy reverence upon elders. This was true even when Sovereign was little, as he always obeyed and respected his parents, even if he disagreed with them. (Mr. Ocean obeyed them less so--not because he didn't love or respect them, but because he is neurodivergent and genuinely struggles to follow directions...)
Champ has certainly met Vex...in fact, he's probably spent more time with her than any of his other kids. But this isn't exactly "quality time", it's more like Vex constantly gets herself into serious trouble and Queen Machine says, "JUST WAIT UNTIL YOUR FATHER HEARS ABOUT THIS!"
So Champ has to drag his ass into the nursery like every other day to scold this kid, hoping she will respect him enough to obey him.
Spoiler art: she doesn't. Because she is smarter than him and she knows it.
Champ is a busy guy, his babymommas know he doesn't have time for nursery business and try to do all the child-rearing themselves. But Vex is his most exceptional child, that entitles her to a little more attention, and the trouble she causes is so above-and-beyond what a normal child does that gets Queen Machine squawking for Dad and even Grandpa to come fix it, because she is totally overwhelmed with this shit.
Most cecaelian children get punished for roughhousing or sneaking desserts. Vex gets punished for blabbing confidential information about her government and starting diplomatic incidents.
One time she trespassed into hostile territory and was eaten by a sacred orca, forcing her father's troops to kill it and free her from its stomach. This deeply offended the enemy tribe, and Sovereign was forced to war with them before he was prepared, losing thousands of troops and hemorrhaging millions of GP in the process.
You know, just average kid shenanigans.
