Take your pick. Scootaloo being seemingly dismissive of her Rainbow fandom as darkoverlords mentioned. Rainbow seemingly acting like Scootaloo isn't allowed to enjoy any other fliers than her. Lightning Dust being a butt. Lightning Dust not being redeemed. Twilight not flexing her princess authority to solve the issue. The list goes on, and then they use it as an excuse to dredge up their problems with Wonderbolts Academy (Another episode I loved) and the whole thing just degrades into a colossal flame war.



We already saw this happen with A Matter of Principals, only the dredging there was with literally any Starlight or Discord episode.
