i think its very posssible that near was responisble for misas death at the end of the anime.
since he was shown to be the last one in possession of the death note, also he could have wrote misas name into the death note to make sure that there wasnt anyone else who knew of the death notes exisitence who could still use it aside from the SPK and the aizawa group who would never use the notebook anyway.
plus does anyone find it weird how she dies at the exact moment in time that light had died? and i know that anyone reading this is going to point this out:
How would misa be able to transport herself to that building to jump off at the same time as light was going to die?
that whole light running scene could have taken about 20 to 30 minutes to do and by that time misa could have already been on her way to that building, OR since Near was already in possession of the original notebook since the beggining of the episode before the last episode he COULD HAVE written misas name into the death note before going to the warehouse to meet up with light and his group. inside the note if it exists could have been written like this:
Misa amane-Suicide
jumps of the edge of a building once light yagami dies
However this would be impossible becuase no one would be able to know that someone else is dead without being notified or being there in person to see that persons death, Or since near KNEW he was going to win anyway he could have written in the time of her death as well. of course what he didnt realize is that Misa no longer has memories of the death note, completely making her innocent. if Near found out about the Memory erasing thing then that could completely CONVICT Misa amane, i have a bunch of other theorys but my brain cant bring them up right now becuase there are so many.
if i could live in RED DEAD REDEMPTION, my name would be VASH THE STAMPEDE
