Olly has good genes, he's the golden child of the family. He has good discipline and somehow a good raising, Nightmare sees the good in training strength while Fresh sees the good in training your mentality, the two have a good balance, but it gets too chaotic when intervened wich makes it risky. Olly is far off from "good", he's just like his parents but more composed, disciplined and well-taught, but weaker, much much weaker. Yet, he can be a great opponent depending on the situation, he's still young, he will get better eventually.
How did it happen? more like a deal, Nightmare needed heritage and more "loyal allies", Fresh was a good choice, they have a lot in common somehow (past the villain/hero thing because that doesn't fit Fresh at all), they just kinda went along with it and it became domestic and somehow romantic. Sorry yeah no sad angst, i like happy domestic love stories on my ships no matter how evil these mfs are LMAO. At first it was a more "its just a deal for alliance" then it went to "youre useful, i'll keep you around and protect you because i don't feel disgusted by your presence unlike the others" then to "you're better than anyone else i've known" to "we are in love but i won't admit it yet we are married and have a family but let's not talk about it and just show it in other ways"
Nightmare def has favouritism, he does not hide it at all✌Yes, Oleander has a sibling! But not from Nightmare, from Fresh, Fresh had a child with Greaser first. LOL you already know the story with Greaser, didn't work out AT ALL! But at least Nightmare saw it as experience points. The siblings dynamic will come soon with lore and ect after ref sheet comes for the sibling!2!2!2!2!2!!!!OK BYE
