"It doesn't do anything!" Cole complains, giving Rita a frown. "Everything else moves, so I thought everything else was all there is."

Which doesn't really explain much. How did he not notice it, he didn't have to move the creepy squid tentacles so he didn't pay any mind to it. Good job, Cole. Still, she says she can help so Cole's instantly grateful that Rita can and will help.

"Thank you," he murmurs. He's staying still, though. Cole's got no idea how to make these things work, that's all for Rita to take care of and for Rita to boss him around.
