'Supergirl' Reveals a Big Secret About J'onn J'onzz

The CW

In the previous episode of Supergirl, M’Gann M’orzz psychically called out to J’onn J’onzz, begging him to return to Mars. And it turns out that was because she and her recently acquired allies, other White Martians who were sympathetic to the plights (or, rather, the genocide) of the Green Martians, found one particularly important Green Martian still alive and in a labor camp.

J’onn J’onzz’s dad, Myr’nn J’onzz, is alive.

This post contains spoilers for Supergirl Season 3, Episode 3, “Far from the Tree.”

“Myr’nn J’onzz is the high religious leader of the Green Martians,” M’gann explained to Kara Danvers’ Supergirl (Melissa Benoist) in “Far from the Tree” as J’onn (David Harewood) kind of totally loses his mind over the reality that his father is alive. J’onn had thought he’d lost his entire family — including his wife and two daughters — in the Martian genocide; being reunited with his father, who doesn’t believe at first that J’onn isn’t a White Martian trick, is obviously overwhelming.

One of M’gann’s recruits adds that, “Not even the worst of the Whites would kill the Prime Servant of H’ronmeer,” meaning Myr’nn is a servant of the Martian god. Apparently, the White Martians also kept him alive because he knew the location of a religious relic, a psychically charged staff that would help the White Martian leaders detect dissenters and any remaining Green Martians (aka, J’onn).

J’onn convinces his father that he’s not a trick via an emotional yet painfully simple memory: his daughters playing in their home before the White Martian attack. Kara, whose story and ongoing grief over the events of the Season 2 finale are put on the backburner for Episode 3, helps her father figure’s father understand, as well, playing a large role in reuniting a broken family.

After a brief fight scene — which consisted mainly of CGI Martians kicking each others’ asses and Kara occasionally flying around and looking cool — Kara and J’onn take Myr’nn back to Earth, where he will now live out the rest of his life with his son.

Meanwhile, proving that this week truly was the episode honoring absent fathers, Maggie (Floriana Lima) reunited with her father. Early in the episode, she revealed to Alex and Eliza, Alex and Kara’s mother, that her parents kicked her out at 14 years old, abandoning her for admitting she was attracted to women. Maggie attempted to reconnect with her father in this episode, only to be abandoned again when he saw her being affectionate with Alex at their engagement shower.

“Thank you for coming to the shower,” Maggie later told her father as she said goodbye to him for the last time. “You gave me an amazing gift: you showed me thatI’m not that scared little girl in that picture anymore. I ‘m an adult woman and I’m comfortable in my own skin… I don’t need you to like me. I don’t need anything from you.”

Maggie’s story might not have turned out as positively as J’onn’s, but at least she now has another family to look after her and love her no matter who she loves.

Supergirl airs on the CW on Mondays at 8 p.m. Eastern.
