is there a mikoto fell theory?

i know there was one for muu that turned out to not be true, and yuno already had the confirmed falling in her video, but in meme, he slides around in puddles a bit (personally, i would think maybe sliding off his bike in a wet area while exhausted, which would explain why he wouldn't remember the incident). combine this with subway theory, and one would think at least one of his incidents was entirely an accident.

not that this explains the baseball bat or anything; i just think since he has a lot of victims, we will have different types. another theory for the pile?
