>> Grant a friend one wish (Augustine fulfilling May's wish to go to a wrestling show)
>> Find someone who broke into Retrospec and slap them (Also, I think this is part of the "Start a rumor with someone and spread it to at least five people" part... Does sharing it through a Retrospec post counts toward four other people?)
>> Share a memory you've never shared before with a stranger (He didn't share that memory in the thread to anyone, including in the thread when he obtained that memory)
>> Go to the Towers and purchase something from Jim's registry to be sent to Jim
>> Share a difficult Retrospec memory (He shared a memory when he Mega Evolves his Garchomp, which since he has no knowledge of Pokemon or Mega Evolution, he can't even explain about this memory)

I think if those bingo squares are approved, I think I'm qualified for a memory regain since one of the thread involves him meeting a stranger. (Proof)
