I suspect we'll be seeing much more of her in Season 4, as Dash and Twilight have had the most drive behind their long-term continuity, and Dash's is the one with the most need for some kind of resolution now that Twilight has already ascended to Princesshood. The question for me is, can Dash ever become a full Wonderbolt and still hang out in Ponyville most of the time, or is it a full-time gig?
