i headcanon that either zane’s a half brother to captain and baron, or that he was simply adopted into the zaford clan cause of how aggressive his brothers were to him. or even that the zafords and the flynts allied and zane just migrated over to the zafords fairly early on. either way, i see zane just practically being raised by the zafords and just seen as one of their own.
i’ve heard some people suggest he fakes his accent like moxxi does, but idk, i can just see the zafords taking a liking to him/just straight up rescuing him from his family, and that’s how he got his accent and phrases and whatnot.
tho i think the headcanon i lean towards the most is that his mom was a zaford and his dad was a flynt, who was baron and captain’s dad as well. if i recall right, zane seemed to have a more positive reaction about his mother over his father? at least it seemed like there was more acknowledgement of a relationship with his mother over his father.
honestly, i loved the zafords so i may have a bias in my headcanons!
