Reunion

This episode was shown out of order as evidenced by the facts disclosed in the plot.

Their adversary supposedly has the ability of a chameleon. A chameleon camouflages itself, seemingly 'melting' into its surroundings. On-screen, from what is seen, this Cameron chameleon-guy, however, appears out of nowhere. He is, in fact, invisible, never simply camouflaged. Also, Barbara reckons he would have the powers associated with a chameleon: strength and speed. Which is not what comes to mind when observing a chameleon. Strength and speed in a chameleon lies in its tongue, which darts out like a lightning strike. What they have in abundance is agility and a highly flexible tail. And, yes, they're not really sluggish, it's basically an act. But from what is heard, the writer of this episode has misconceptions about chameleons. They are vulnerable little creatures that have to remain hidden, their only real defense.
