We stumbled upon a cosplay convention at the park where we had our wedding photos taken. There were zombies and unicorns and one guy dressed as an SS Guard. Mario and Luigi were much more fun.
What better time to pop the question than after saving Kanto from Giovanni's reign of terror, freeing the gyms from Team Rocket, and rescuing all the kidnapped victims, including the rival's wife? That is, of course, you unlock the secret ending.
Hopefully you'll let Team Rocket blast off to the wedding. I mean, that way at least it won't be boring!
