dude, Nakai and his partner need to work together in the same room the way Mashiro and Takagi do.
problem is, nakai is a pervert and that girl is a bit too pretty for that. He is good with manga, thats it...
It would not surprise me if Eiji becomes the most popular first and used his "power" to cancel Trap.
when bakuman begun i thouight this would happen too, but right now eiji and mashiro are friends/rivals. You don't just use cheap moves to beat your enemy, you beat them with your own power, in other words, he is going to be so popular that trap will never reach him again. (imagine onepiece and naruto, onepiece got twice as much votes as bleach/naruto)
but crow got a bit problem himself, with the new assistent being not so good at backgrounds and...not yet understanding what he means with his sound-effects XP
but this chapter showed us a big problem that i think might affect the future, mainly that mashiro can't keep this up. He still wants to improve, but as a fulltime mangaka you can't sit back a few hours and practice drawing, and so he needs to cut time on sleeping, and thats even worse.
