Turns out to be a lot worse than I imagined. So this goes to the scraps and a remake is scheduled.
Update: I tend to believe that the episode "I remember you" has some strange hypnotizing powers that makes it stuck in my brain and causes series of super-fangirl headcanons. I'm considering making a short comic to PLEASE GET RID OF THESE FEEELINGGGGS PLEASE!!!!
Update of update: I DID IT!(At least a part of it, sorta). I have written the plot of the upcoming short comic that literally would fill in the theory gaps (and loads of headcanons). What's left to do is making it down to the paper and glob I'll start working on it after my Nov.7's examination... hopefully, I think. JUST WAIT AND SEE. THANK YOU ALL!
