It couldn't be more obvious to me through Erwin's dialogue that whoever killed Gunther, was the Female Titan as he said they had probably prepared their uniform and 3DMG beforehand. He goes on to say that if they came out of their form, they might be able to transform once again, and that's exactly what happens. It's later revealed that Annie is the Female Titan, so...

I don't see how it was blurry at all.
