Supergirl: [SPOILER] Debuts As Your Favorite Neighborhood Bartender

SPOILER WARNING: This article contains spoilers for tonight’s episode of "Supergirl," titled "Welcome to Earth," which has not aired on the west coast as of publication.

"Supergirl" continues to cruise through its sophomore season, making up for the sorely missed Cat Grant with plenty of fun fan moments and a surprise or two -- watch President Marsdin's eyes! Still, the biggest moment was one that followers of entertainment news knew was coming: "Supergirl" is now one Miss Martian richer.

Played by Sharon Leal ("Grimm," "Hellcats"), M'gann M'orzz turns up first (and undetected) as a bartender at what's clearly the coolest location in the Arrowverse, an alien-friendly dive bar that loves Dolly Parton. After a friendly confrontation with the President about why he still doesn't embrace his true identity, J'onn heads to the bar for a drink and some time out of his Hank Henshaw drag. When the woman we now know is M'Gann sets eyes on him, she becomes visibly upset and heads for the door. Only when J'onn follows her outside does she reveal her true identity: she's the self-described "Last Daughter of Mars," and J'onn is perhaps not as alone as he thought.

Check back later tonight for CBR’s full recap.

Starring Melissa Benoist as the title character, “Supergirl” airs Mondays at 8 pm ET/PT on The CW. The series also stars David Harewood as Martian Manhunter, Mehcad Brooks as Jimmy Olsen, Chyler Leigh as Alex Danvers and Jeremy Jordan as Winn Schott and features appearances by Calista Flockhart’s Cat Grant as well as Tyler Hoechlin’s Superman.
