User blog comment:NickFusi0n/A Theory on The Coordinate and The Wall Titans/@comment-24930713-20140526063156

I called them cowards in relation to anon's theory. If they really were on humanity's side. Then later changed their mind to save their own lives. Instead of helping Eren fight the titans. Then they are indeed cowards.

I personally believe they are in cahoots with the beast titan.
