Guys. I think I figured something out with 4Piece , obviously it's called 4 piece and there are 5 trainees, and not only that, the chapter is called "something Hell", and we can also hear things go horribly wrong in the background of the teasers (like explosions, etc), basically, I think it's going to be a very toxic work place enviorment, and they're either going to make the plot centre around the 5 trainees wanting to work together to become one unit(and having to fight for that), or make it so they have to get rid of one person. anyways, ensemble101 innit?
I saw a post about TMNT with no tags and they refered to the turtle as 'Leo' and I was like hehehe enstars Leo, he- wait he had what? WHO'S DONNIE ? Leo and "Donnie" are ? wait ? SHELL? ok what? and then realised it was in fact, a TMNT post.
