Episode 19: Hearthbreakers

There you have it! The only thing I'm slightly confused about is the episode called "Scare Master" not being aired during October like everyone thought. I don't know if the dates are mixed up or not, BUT I'm so excited to see the Pie family, it's been a long time since we've seen them all together. And Limestone and Marble will be grown up too! 
I'm excited for Brotherhooves Social!
season 5 episode 20 synopsis is up now too might want to add that to this blog
3398911 Already done
3398918 yay
I'm guessing Big Mac has to dress up like a mare.
I can't wait to hear what Pinkie's family is gonna sound like.
Episode 18 airs on my birthday!
3399024 ...Again?
When I first read the synopsis, I thought it was about how the Pie family celebrates Hearts and Hooves day on the Rock Farm, and I was sure the plot would be about accepting Maud and Tom as a couple.
3399748 Eh, nevermind.
3399748 I've never seen Big Mac dress like a mare.
3434495 Magic Duel, Twilight disguises Big Mac as Applejack to fake a gender-switching spell.

3434552 Good point; I remember now. Also, did you check out the trailer for Brotherhooves social?
3434560 Not yet, I didn't realize it had dropped.
3435087 Also, Big Mac was still stallion, just a genderbent form of AJ.
3436173 Right, he was just disguised as a mare, he didn't actually turn into one, apparently that's impossible.
3436236 Technically, the way I see it, he's still a stallion.
3436239 Of course he is, but he's dressed as a specific mare.
3436286 Eeyup. Sorry for dragging this out much longer than it needed to be.
