Good, the Yeerk was thinking Marco was just stupid (he could almost hear Rachel's voice in his head, telling him that no, he was stupid). Now he just had to make sure he didn't make the Yeerk realise otherwise.

So, he just worked on looking abashed and reprimanded, like a good little Yeerk soldier would.

"I...I'm sorry Sub Visser. I promise I won't fail again."

Marco couldn't wait to watch the Yeerk starve.
