SPOILER WARNING: This article contains major spoilers for "Paradise Lost," the latest episode of Supergirl.
Supergirl's Martian Manhunter is getting back to his roots. In "Paradise Lost," the latest episode, J'onn made his first steps towards becoming an alien detective.
In the episode, J'onn introduced Kara to his friend Amadei, an alien healer. However, no sooner had Kara run an interview with Amadei than an attempt was made on his life. His gem was stolen and, without it, he would die, so Kara and J'onn embarked on a mission to find it and save him.
J'onn and Kara soon discovered a terrible truth: Amadei's ex-girlfriend and the mother of his child had pointed the Children of Liberty towards him. The Children of Liberty gave the gem to former DEO Agent Jensen, now the host of Parasite, in an effort to enhance his powers. Fortunately, Alex was able to talk Jensen into relinquishing Amadei's gem. With it, Kara and J'onn were able to restore Amadei back to his old self.
The mission complete, J'onn retired to the alien bar for a drink. As he nursed a glass, the bartender approached him. He explained that another patron had been looking for him; specifically, she hoped J'onn would help her track down the vandals who were covering her shop in anti-alien graffiti. As he slipped J'onn a piece of paper with the woman's phone number, the bartender revealed that other aliens considered J'onn the person to go to when they weren't comfortable reporting to the cops. At that, J'onn smiled to himself and dropped a fedora on his head.
In the comics, of course, J'onn was a detective in the fictional town of Middletown. After he was stranded on Earth, he assumed a human face and the name "John Jones" -- an Anglicization of his Martian name -- and found a new life as a police detective. As pictured above, he also rocked a fedora much like the one he put on at the end of "Paradise Lost." This suggests he will assume a similar role on the series, especially seeing as he officially stepped away from the D.E.O.
Airing Sundays at 8 pm ET/PT on The CW, Supergirl stars Melissa Benoist as Kara Danvers, David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, and Chyler Leigh as Alex Danvers.
