Inspired from an excellent headcanon I saw yesterday on tumblr! -> [link]
Well, since the plot of this digimon half season was so screwed we only know Astamon somehow got possessed by that ugly thing called Quartzmon and then R.I.P. But exactly how?
Ah headcanons are many but I particularly fancy this recent one: what if Quartzmon stayed on Astamon's head and pestered him in purpose the WHOLE time until the last episode?
Ahahahah poor thing that's worse than sudden death XD
