YMMV: My Little Pony: Friendship Is Magic S2 E14 "The Last Roundup"
Broken Base: This episode has joined the likes of "The Mysterious Mare Do Well" as one of the series' most divisive episodes. Strangely, it wasn't due to the events of the episode itself, but Derpy's cameo, both before and after the infamous edits made to her appearance. Was it a nice tribute to the fans of the show, obnoxious pandering to those fans, possibly offensive to disabled people, or all of the above? Things got at least 10 times worse after the editsnote Which edited out Derpy's name, changed her voice, and switched her crossed-eyes to correctly aligned eyes. that were made. AND THAT IS ALL THAT WILL BE SAID ON THE MATTER.
There are some who consider the episode to be very tedious due to it's predictability as well as the contradiction of Applejack being the Element of Honesty. (and to a lesser extent the contradiction of Rainbow Dash being the Element of Loyalty due to leaving Pinkie Pie and Rarity behind)
While there are some fans who want both the defenders and the detractors of Rainbow Dash and Applejack's actions to get over it, stop demonizing Dash, and move on.
Epileptic Trees: A lot of people began making theories that Tonight Someone Dies or gets Put on a Bus with this episode, presumably because the word "last" is used as part of the episode title. "The Last Roundup" is a term best associated with death. note "Last roundup" tends to be used for when a cowboy is soon to die.
That said, the very next episode was already confirmed to be another Applejack based one, so it was easy to disprove any such theories, though considering all info given about that episode before this episode mention the Apple Family, but not Applejack herself.
The fans, after hearing Rarity's vow of vengeance, quickly assumed that she was the reason why Rainbow Dash was in the hospital in "Read it and Weep". When the episode premiered, it turns out to be her crashing.
The method of the revenge Rarity promises against Rainbow Dash is a popular fanart topic.
Pinkie and Rarity's trip back on the handcar. The two characters are rarely paired up with each other and the stories usually play out like the Family Guy episode Road to Rhode Island.
Pinkie's reaction to a "Pinkie Promise" being broken...
Harsher in Hindsight: Compare this episode where Granny Smith says "Our little bushel just lost one apple" (in reference to Applejack's desertion) while Big Macintosh and Apple Bloom sob in the background. Mildly sad at the time, but absolutely heartbreaking after "Apple Family Reunion", where it's revealed, albeit implicitly, that Applejack's parents are dead.
Heartwarming Moments: Fluttershy and Twilight Sparkle: "We can always find a way to fix the hole in the roof, but if you don't come back who's going to fix the hole in our hearts?" Even the tomboyish Rainbow Dash shed a tear at that line.
Hilarious in Hindsight: Back in "Sisterhooves Social", we had Rarity calling out Sweetie Belle for causing damage, and this time it's Rainbow Dash scolding Derpy. Extra points for a variant of "don't do anything at all" being said each time. Extra extra points for Rarity and Derpy sharing a voice actor.
Overshadowed By Controversy: This episode appears to be only remembered just for Derpy's cameo, canonization and subsequent de-canonization. Virtually everything else about it is quickly forgotten.
Stop Helping Me!: Derpy's efforts in setting up Applejack's sendoff party end up doing more damage than anything else, and are what ultimately set off the events of the episode.
Tear Jerker: The Apple family's reaction to Applejack not coming back is pretty heartmelting (particularly Apple Bloom), as is Applejack admitting in defeat her reason for avoiding her friends, she didn't come first in any event, and considers herself a failure because of it.
Becomes even more of a Tear Jerker, as well as Harsher in Hindsight, when watching the episode after seeing "Apple Family Reunion". In that, everypony in the Apple Family makes an appearance... except Applejack's parents, who confirmed to be dead. Now watch that aforementioned scene again ad realize how heartbroken the Apples must have been at the thought of losing another family member...
Wangst: It can be a little hard to feel pity for Applejack being rude to her friends, breaking a Pinkie Promise, and leading them on a dangerous desert chase, just because she didn't win first place.
Jerkass Woobie: Both the above and the below tropes paint Applejack in a flawed, but sympathetic light. Her actions are all in good intentions but she has a prideful and misguided direction to it.
Also, as Applejack herself points out, she didn't actually break the Pinkie Promise: she told everyone she'd tell the truth "at breakfast", so since she was never at breakfast, she didn't have to tell the truth.
The Woobie: Applejack. Just listen to how downright heartbroken she sounds revealing how she failed! She feels like she's a complete and utter failure for not getting the awards the town expected her to.
The poor telegram pony; it was his birthday! Fortunately, Pinkie eases his disappointment.
