Endless possibilities, so little time.

You know, one thing that I've never understood is why exactly Annie killed the two Titans that were captured in season 1 of AoT. I'm up to date in the manga, so unless I completely forgot the answer, it's always been an unanswered question. Sure, the obvious answer is that she didn't want the Survey Core to discover more information on titans.

We know that titan shifters reside in the nape of a titan, and the nape is of course their weak spot. So, is it possible that Annie killed them, because she doesn't want the Scouts to discover that MAYBE, a person can be extracted from the nape of a mindless titan?

Ymir remembered her dreadful 60 years as a mindless titan, so is it possible that many answers may be answered via the trapped souls within the mindless titans? Remember that the blonde woman who was turned into a titan just seconds before Ymir suffered the same fate? When she was a titan, she thought that Ilse was Ymir, resulting in the titan showing intelligence. So in a sense, her human form momentarily "woke up" from the mindless titan nightmare. Hoping that by killing poor Ilse(thought to be Ymir) would turn her back into a human.

Who knows, maybe Annie will spill the beans when she fucking finally eventually comes out of her crystalized state.

If this turns out to be the case, then OH MY GOD!
