User blog comment:NickFusi0n/A Theory on The Coordinate and The Wall Titans/@comment-25358468-20140522214517

Everything you said apart from the last paragraph was quite obvious, I'm glad it got somewhere haha. I never thought of that, good theory. It's probably not even a theory, it's undoubtably true, if Eren can control Titans, he more than likely can control the ones in the walls. Reiner said that the Coordinate was in the hands of the worst possible person - obviously someone who would never touch the walls. It's crazy, once you think about it; the walls were created to be destroyed. Humanity was trapped in them by the Titans.
