Linda Lee/Snowbird notices an AmerTek pin on a patron. In DC Comics, AmerTek Industries is a military industrial firm that employed engineer Dr. John Henry Irons. Irons is the engineer that developed the BG-60, a powerful man-portable energy cannon, which is sold to urban arms dealers by AmerTek. When Irons learns that his invention has been used for evil purposes, he destroys the blueprints, quits AmerTek, and starts his own business, Iron Works. At Iron Works, Irons designs and builds a prototype of the armor that will eventually become the "Steel" armor. AmerTek spies steal the blueprints and use them to create their own knockoffs. In their actions, they purposefully target civilians, namely John's family. See more »

Fantastic episode!
26 March 2019 | by RobinKarlsson22See all my reviews

I love this episode! It was (perhaps) the best Supergirl episode ever. We finally got to learn about Red Daughter and see what Lex has been up to. If you like them then this episode is for you. And Melissa is such a good actress.
