Kara helps Mon-El adapt to living on Earth while J'onn deals with finding another Martian. Meanwhile, Alex and Maggie investigate an underground fight club for aliens.
Tropes
- Double-Meaning Title: More like a triple meaning: Kara and Mon-El are survivors of their worlds; J'onn and M'eggan are the last ones of Mars; and Roulette boasts only one survivor can win her fights.
- Mythology Gag:
- Roulette looks just like the comic book character, complete with the snake tattoo under her red dress.
