Spike sneaks into Zecorah's place and 'borrows' a special flower. Smelling it will make 당신 fall in 사랑 with the first person 당신 see. Obviously he tries to get Rarity to smell it, accidentally infecting everyone in ponyville in the process. Eventually everypony's chasing Spike in a lovestruck stampede, causing Celestia to come down from her 성 to see what the ruckus is about. When she too smells the 꽃 and falls in 사랑 with Spike all hell breaks lose.
Spike is forced to ask Zecorah for help. She creates a 담홍색, 핑크 구름, 클라우드 of fog, that cures everypony. Luckily for Spike nopony remembers a thing. In the end he writes a letter to Celestia, about how 사랑 is something that cannot be forced.
