The girls tail their professor as best they can, Cammie and Bex doing much better at field work than Liz. The carnival provides lots of crowds to hide in and ways to appear nonchalant, which helps Cammie live up to her chameleon nickname. Liz loses sight of Cammie while she sits in plain sight because there’s nothing to draw attention to her, and Cammie notes that if she’s still and calm, “it's really easy to be invisible” (70).

At one point, the professor almost spots Cammie when she helps an older woman who tripped. As the professor walks away, the woman asks if she knows Cammie at the same moment Liz asks if they still have eyes on the mark. Cammie answers yes to Liz, but the old woman thinks Cammie is talking to her and mistakes Cammie for someone else. She asks another question, and Cammie gives a response that’s also a warning to Bex that their professor is closing in on her location. Cammie hears Bex curse and then loses visual on her, too.

Not knowing what else to do, Cammie heads to the funnel cake booth, where she finds their professor yelling at Bex and Liz for being off campus without permission.
