Baby Flurry Heart (Left): prancing for something. (Note: I recreated the pose from "A Flurry of Emtions" where Twilight is giving Flurry a surprise after the intro, of course.)

Filly Flurry Heart (Middle): Watching her younger self, chuckling quietly.

Adult Flurry Heart (Right): Watching the two, smiling for remembering her past in Nostalgia.

Also, There's a little thing called 'Remembering your younger self' that Flurry Heart came up with... so, as she grew, she uses her magic to open up a portal so that she'll meet her younger selves... just to remember the good times she had with the old family of the Crystal Empire.
