Role
After Helen rescues an ambassador from the Screenslaver’s clutches, she manages to defeat and unmask the villain, who is revealed to be a pizza delivery man. The pizza delivery man claims that he is at a loss for what was happening. During a celebration at the Deavor's, Helen realizes that the hypnoscreens the Screenslaver has made are also within his goggles. Soon thereafter, the goggles are forced onto her by Evelyn Deavor, Winston’s sister, brainwashing Helen. Evelyn reveals herself to be the mastermind behind the Screenslaver; stating that she despises superheroes and sees her brother's mission as a threat to humankind's independence. Evelyn then tricks Bob into 'rescuing' Helen before the hypnotized heroine forces another pair of hypno-goggles onto Bob, putting him under Evelyn's control as well. Later, Frozone also ends up captured and put under Evelyn's control, although the Parr children evade capture themselves.

Dash, Violet, and Jack-Jack, whom Edna had fitted with a super suit, sneak aboard the Deavor's ship where there is a hearing of leaders to re-legalize superheroes. Jack-Jack removes the hypno-goggles on Helen, who then frees Bob and Lucius and reveals Evelyn's plan to the assembled leaders. A battle on the boat ensues threatening to crash the ship into New Urbrem. However, the supers manage to stop it and Helen apprehends Evelyn when she tries to make an escape.
