Where do you Lena used to live at between her return in "Friendship Hates Magic" and being adopted by Violet's parents in Season 3?
If Violet (and Lena) has two fathers, then what about her mother? What do you think what happened before? (Like Violet's family background - e.g., How did she "earn" two fathers?)
What would you like to know or learn more about Gandra Dee's background? Like her family?
How many centuries do you think Scrooge would remain himself as a adventurer?
Is Goldie O'Glit immortal either like Scrooge?
In the series finale, do you think Bradford should have hired Glomgold, Ma Beagle, Mark Beaks, Lunaris and other non-F.O.W.L. villains (except for Magica because Phantom Blot is in it) to join him instead of letting Steelbeak used them as his slave-weapons?
What the series should/could have done better?
