Against common belief, the Scorpius Rex is named after not the Skorpiovenator, nor any kind of scorpion at all. It's quills and name come from the Scorpion Fish.
The title of this episode, "Clever Girl", is one of the most famous quotes from the original Jurassic Park (1993) film. This line is said by Robert Muldoon when he is ambushed by the velociraptors as he himself had been attempting to ambush said raptors. The title is also an indication that this episode involves raptors or, in this case, the last remaining raptor, which is Blue.
