Well, many things did not make much sense on this chapter:
 * Levy. Why is she still on Cube while the others are not? The reason this bothers me so much is because it will be probably left unexplained, like a bunch of other plot points in this arc.
 * Why did Gajeel not suffer the same fate as Natsu despite having his mouth wide open?
 * How come Levy be able to hold her breath for a longer time than Gajeel, swim to his place and also give him air?

Despite being a decent chapter, it was too weak on common sense, and that's something that really bothers me when it happens.
