I hope not... I don't need another McDuck to deal with!

I don't think so, but I do think her relationship with the McDucks could be stronger if we knew more about her parents.

No; it's not like the Duck/McDuck/Coot family is the only family of ducks capable of going on adventures and fighting to save the world. And any similar features between her and, say, Matilda, could easily be coincidental.

No but im glad she's not a McDuck. I really like her as a family friend

Not sure yet

I think that Pepper is Webby’s long-lost mother and that Daisy is raising her long-lost sisters, May and June.

Can't believe you got it right :0
