Ryan and Hector
Had the twins had the ability to break the fourth wall, they would be so pleased that they actually tried to carry out a secret mission without standing out so much. But it wouldn't have helped. One of the yeerks saw them.
They helped dragged Cody's mom back to school, via back alleys. It would do no good to drag a body around in full view.
Hector frowned at Sierra, as he and Ryan dragged the body back. "Next time, don't get in the way. I'm just going to kill them. No interrogating, no nothing. The mission was jeopardized. If I killed the yeerk straight out, then we wouldn't have to worry."
Ryan kept quiet, he too had a part of the guilt and blame. Had he been quicker, their cover may not have been blown.
