In My Little Pony Friendship is Magic is a season 6 episode  in which Fluttershy's brother will debut. Likewise, Gloriosa Daisy is a character debuting in My Little Pony Equestria Girls: Legend of Everfree.
I wonder if Shy's brother will appear in Legend of Everfree in human form while Gloriosa Daisy will appear in Friendship is Magic-as a zebra.
I speculate that Flutterbrother will in the pony universe become a friend of Gloriosa, who lives as a zebra in the Everfree Forest.
I also wonder if in the human world Flutterbrother and Gloriosa will become boyfriend and girlfriend.
