Trixie enters the Everfree Castle of the two Sisters.. and Sticks her tongue out at me XD. I would love to see Trixie make a comeback in Season 6. and I'd like to see backstories on some of the Ponies. more in depth ones. and to finally find out if FLuttershy is somehow related to Scootaloo, since we've never seen their families.
I tend to think that Flutters is Scoots Mom. Since their colors are close.
