Dru tells Gru about their father, one of the greatest villains of all-time. They talk about their family tradition of being a villain, and Dru asks Gru to teach him to be a villain since he is considered a failure. Gru declines the offer, as he has left that life behind, but he takes a ride with Dru in the villain vehicle after Dru's tempting presentation of it.
Larry and Amelia consult the Einstein bobbleheads for help on finding the secret at the heart of the Pharoah's tomb. Amelia realizes that the answer is Pi, and the Einsteins state the value of Pi since Larry doesn't seem to be familiar with the constant. Important to note is that Pi is not exactly the value stated by the Einsteins; it is approximately that value.
