Spike sneaks into Zecorah's place and 'borrows' a special flower. Smelling it will make আপনি fall in প্রণয় with the first person আপনি 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 দুর্গ to see what the ruckus is about. When she too smells the ফুল and falls in প্রণয় with Spike all hell breaks lose.
Spike is forced to ask Zecorah for help. She creates a পরাকাষ্ঠা মেঘ of fog, that cures everypony. Luckily for Spike nopony remembers a thing. In the end he writes a letter to Celestia, about how প্রণয় is something that cannot be forced.
