Chrono Crusade/Headscratchers

• In the Anime: What the hell Chrono? Why don't you use the horns you got back from Joshua? Why are you THROWING THEM AT PEOPLE? Then you would have been able to do what Rosette asked towards the end!!

• Aion has demonstrated that he removed his horns. The question is brushed upon in the manga, but who is his contractor in the anime?

• When Pandemonium tries to change bodies in the end of the Manga, Aion laughs and says that she has already destoryed any body she could have taken over, the page jumps to a cut of the contaminated demons. My question is, if Pandemonium could have taken over other demon bodies, why did they need to kidnap humans in the first place?

• Okay, so it is revealed in the manga that Aion already beheaded Pandemonium 50 years before the start of the manga. So, how is it that Pandemonium is still intact in the final issue?
