The Female Titan, one very ferocious titan which knows exactly what’s she’s doing. From what Armin thinks and knows, she’s going directly for Eren, which is again correct. She could be anyone and we wouldn’t even know it. For those who only watch the anime, you won’t know the person. However the manga has progressed so much that the identity has been revealed, plus many more titans have been revealed. Wink, Wink.
