It’s a bad time to be an alien on Supergirl.
As Project Cadmus has all but declared war on beings who are not of this world, President Olivia Marsdin (Lynda Carter) plans to sign an alien amnesty act during Monday’s episode. But when an attack is made on the president, Kara (Melissa Benoist) fears that the newly arrived Mon-El (Chris Wood) may be to blame.
“He’s the prime suspect [of being] this assassin that’s trying to kill the president,” executive producer Andrew Kreisberg says. “The last thing Mon-El remembers is being on an alien world, he jumped into a pod, and suddenly he wakes up on a strange world. He’s all alone, he’s surrounded by people with guns and he’s having a reaction. He’s reacting to the fact that he suddenly has superpowers, which he wasn’t expecting. How that story weaves about and how he and Kara come together by the end is hopefully pretty clever and interesting.”
For now, Kara and Mon-El are not aligned. After all, Mon-El did choke Kara upon waking up at the DEO at the close of last week’s episode. But the palpable tension goes back even further than that. “We’re going to explore, in our universe, the idea that Daxam and Krypton were sister worlds, but they didn’t really get along,” Kreisberg says. “As somebody says, it’s sort of the Hatfields and the McCoys, so there’s a lot of innate hostility that Mon-El and Kara have for each other simply because of their backgrounds, which is interesting because Kara is not exactly on her best behavior. We always think Kara is so interesting when she’s flawed and watching her learn and grow.”
Eventually, though, Mon-El will help fulfill Kara’s original mission of looking out for Kal-El. “Now she has somebody to mentor,” Kreisberg recently told EW. But the question is: Can he be trusted? “Can you trust anybody?” Kreisberg countered.
