i figured out the reason behind the continuity error
This is the lovechild of Viktor and Logan created
I have a broken sense of humour, so forgive me. But the fact that VICTOR CREED not only fathered a non-mutant child, but also that same non-mutant child became a politician, suit and all. Sabretooth, a man where the word 'Barbarian' comes to mind, fathered a political figure. Granted, Graydon is as much a monster as Mr Creed senior, but the vision is everything.
Can you imagine the shenanigans?
Graydon being forced to go back on his words about his anti mutant propaganda, and talk about how they're not so bad because a list of nice things they done for him in order to avoid getting a spanking.
Graydon opening up about his mutant background, and how his anti mutant propaganda came from hating himself and his mommy issues, and how he learned that doesn't mean other mutants are the same, and using that to advocate for mutant acceptance.
Graydon getting some kind of promotion, and a party being hosted to celebrate it. Then Sabretooth crashes it, gets drunk and starts embarrassing Graydon in front of all his co-workers and fellow politicians. Saying stuff like "Just to think all those decades ago you was in my balls!"
His co-workers recognising that Graydon's cat-like habits come from Sabretooth. Standoffish with people he's just met. Hissing or growling when annoyed. Disturbing people, but not liking when others bother him. Having no concern for other people's belongings. His co-workers noticing how he avoids people when he's stressed, just like a cat.
Getting asked awkward questions at interviews like "Do laser pointers bother you?" and "Do you eat lots of fish?". Graydon trying his best to stay professional and not lose his cool.
Graydon being forced to stand next to Sabretooth, and everyone pointing out how small he looks in comparison despite being very tall, because Victor is HUGE.
Graydon being forced to acknowledge his other siblings from Mystique's side, and coming to the realisation that Logan is his uncle.
Graydon trying to force Victor and Logan to form a momentary truce just so they can take a good picture for the front page of a news paper (for mutant positivity reasons). Many fights ensue, and it takes over 60 attempts until a picture is taken where Victor is holding up a struggling Logan with a grin prepared to throw him, and the headline being "Sabretooth excited to reunite with little brother" or something.
Graydon meeting with Professor X to discuss the needs of mutants, and bumping into his cousin Laura, who hasn't forgiven him for his anti mutant days.
Professor X helping him with his inner trauma, and unpacking the trauma Mystique put him through, and the shame he felt knowing his parents were bad people, and being normal as the only thing he can cling to in efforts to avoid believing he's like them. How Graydon wants a family deep down, and actively hunted mutants to get attention from one or both his parents. How Graydon always wanted acceptance, and being abandoned caused a dilemma within him that lasted decades.
Graydon being forced to spend his holiday in Canada, and staying indoors at a cabin while Victor gathers firewood because he can't handle the snow.
Being forced to embrace his Canadian heritage.
