Charzoid
They really do need to do something with this ship. They've already proven that they can make romances in this show believe able if done right and that they know how to give secondary callback characters flesh. We've seen sci-twi is a bit different then pony Twi so pony flash might be more interesting then human flash if given flesh. I have a feeling though that they may not do anything till the series final season since they haven't had much need to give Twilight much else a princess could have. She's got friends, a castle, a pupil, a pet, an assistant, and the only thing she needs I'm guessing as the finisher will be a boyfriend. With that boyfriend we'll get the main or side main character or characters to G5 after G4 ends and we'll have to wait likely 3 yrs for G5 to happen after.
