This Yeerk surrendered itself willingly: it didn't want to die or to harm anyone else. The Yeerk's fate was decided in trial. I forget about the specifics, it was right before I was brought here, but in any case, its punishment was to be jailed forever on the ship instead of being killed. Some of us didn't think that the Yeerk should be imprisoned, but killed, because of the threat imposed on the ship. I admit a lot of its gotten hazy in memory now, but I was frightened for someone on the ship, and the possibility of being controlled like that. So I tried to capture the Yeerk.

Ax was for imprisoning it forever. I feel like in the end, he knew what the price of just killing it would cost him.

He was right.
