WARNING: Spoilers from Supergirl's “Schott Through the Heart” follow.
Last night’s episode of The CW's Supergirl not only featured an emotional reunion between Winn (Jeremy Jordan) and his mother Mary (Laurie Metcalf), but also a cool easter egg of gigantic proportions plucked from the Batman comic book canon.
During the midseason premiere titled “Schott Through the Heart,” Supergirl (Melissa Benoist), Winn, James (Mehcad Brooks) and Mon-El (Chris Wood) team-up to rescue Winn’s mom from the late Toyman’s (Henry Czerny) apprentice, Jacqueline Nimball (Brooke Smith). When Supergirl gets trapped inside a life-size action-figure packaging (gotta keep the Girl of Steel in mint condition, after all), Mon-El tries to rescue her but is attacked by a huge mechanical T-Rex. Using the giant dinosaur to his advantage, he managed to free Kara from her plastic trap before defeating the T-Rex in an epic fight with the use of a cape.
Now, Batman comic book fans will know that one of the Dark Knight’s coolest trophies to be found in the Batcave is a mechanical T-Rex, which has a place of pride alongside the giant penny and the giant Joker card. Batman acquired the trophy during Bill Finger and Bob Kane’s “Dinosaur Island” adventure from Batman #35, published in 1946.
In the story, Batman and Robin find themselves in an amusement park called Dinosaur Island where they have to survive (in a mock game) fully-functioning robotic dinosaurs and cavemen for 36 hours without using any of their modern equipment; including the Bat-vehicles and the utility belt. When the park is taken over by the villainous Stephen Chase, this one tries to kill the Caped Crusader and the Boy Wonder. The dynamic duo not only managed to survive, but they also captured Chase. Batman subsequently gained a mechanical T-Rex as a trophy and placed it in the Batcave, using it to drive away any unwanted intruders.
Sure, it’s not like Bruce Wayne suddenly appeared in National City and waltzed into the Arrowverse proper — though that would be super. But it’s definitely a fun nod to the official Batman canon. Did you put together the easter egg while watching the episode?
Supergirl airs Monday nights on The CW.
