Erza being put back into action this soon doesn't feel that right. The tension blew away faster than it was made, it took the Prologue and Part 1 to create the current tension and it took one chapter to destroy that tension. Mashima could've break the event in this chapter into 2 chapters. Like pushing Erza and Mira's escape into next chapter.

And why wait for ambush when Natsu could just use his nose to locate Mira's location.
