It seems you know as much as I do of our current objective. [That was rest assured.. Erwin wasn't ready to be face to face with the titan-obsessed scientist that learns just who the Colossal Titan is for the very first time.] Or once objective.

So it is safe to say the Colossal Titan is dead? What of the Armored Titan? No word it seems. They are no use to anyone dead, that information will be lost.
