This petition is for bronies who enjoyed both the show and the Equestria Girls movie.
Just as we bronies fought to save Derpy Hooves from the censors, it is our job to continue to support Flash Sentry. I believe that he should be part of the show, because he is a central new figure in opening up Twilight's personality to her concept of love.
A move like that is a positive development for Twilight Sparkle, aside from having her becoming a Princess after the Season 3 finale which help's the character to be more 3-D with their personality.
If we speek up like when it came to Derpy, because we were able to have Derpy return in Magical Mystery Cure and in Equestria Girls so every Flash Sentry fan and FlashXTwilight shipper should speak sign this petition to bring Flash into the series.
