These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: My Little Pony Friendship Is Magic S 1 E 24 Owls Well That Ends Well
Base Breaker: Owlowiscious. Fans are divided whether he's a cool an funny character who needs more appearances or a pet sue who really seems to covet Spike's place. However "Just for Sidekicks" where he acts more friendly toward Spike may have redeem him for some.
Harsher in Hindsight: Oh boy... this episode suddenly becomes a lot more tragic in light of "The Crystal Empire Part 2" revealing Twilight not needing Spike anymore is Spike's worst fear.
Jerkass Woobie: Despite how Spike acted in this episode, it's hard not to feel bad for him because he felt that he wasn't loved by Twilight anymore. Poor guy. Even more so in light of the Harsher in Hindsight entry above.
