Cool, was wondering aabout Robin's parents
Here's the thing, though - I agree w/"your father" causing less confusion and also it tying in with older sitcoms w/the dad generally being tougher. But, the thing i, we never see either of Robin's parents.
I suspect it's possible Robin's mother died. Kermit might actually take care of Robin quite a bit, which is why we see him there so often. It would explain why we never see eitehr parent.
Or, Robin's dad moved in with his brother-in-law, and his best friend also came to help raise Robin and a couple siblings...no, wait, that's FUll House
(Besides, Kermit be3ing in show biz/comedy would be in the best friend role then.) But, I did have thaat idea as the episodes rolled on and we saw Robin more but never the parents, that Robin's mom was dead & Kermit helped raise him. Because tthat was sort of a staple of some sitcoms, a widower raising kids. ("Full House" was a rare one because they actually referred to the deceased mother and acted like she had once existed.)
No, I will not have time for a fanfic involving Robin's mother's death. Yes, you may steal the idea if you wish.
