Yet the fact of the matter is, whether he understood but chose to investigate first or whether he failed to understand, he simply did not make a commotion. So you cannot argue he would have!

Missile...he attempted something difficult for him. He brought those pictures to K. He must not have known how to play his role, but wanted to stay safe to better protect us...it was those he brought the pictures to who failed him. They failed to understand. And until it had been long enough in the trial, Missile could not have realized they would not speak.

Once he realized, he acted and put his own life in danger to save Legion.
