Supergirl: [SPOILER]'s Identity is Revealed

SPOILER WARNING: This article contains spoilers for the latest episode of "Supergirl," "Crossfire."

The second season of "Supergirl" doesn't suffer from a shortage of new characters, perhaps most notably Lena Luthor (Katie McGrath). To this point, Lena's spent a fair amount of time and energy trying to prove to the world (and to the Kryptonian Super-cousins in particular) that she's not cut from the same cloth as her villainous adoptive brother. McGrath's arrival on the show prompted a predictable amount of speculation -- would this Luthor carry on the family tradition of villainy? -- but to this point, she's done nothing remotely evil. Perhaps that'll remain the case, because as of tonight, we've got a new relative of Lena's on the scene and she's got plenty of villainy all by herself.

Brenda Strong's unnamed Cadmus scientist may not have a name yet, but she's got an identity: Lena Luthor's mother. In the closing moments of "Crossfire," mere hours after murdering her own hired thugs, Strong's character turned up in Lena's office, crashing a meeting between her daughter and Supergirl in the process.

Is this the Luthor matriarch? It's more than likely. Strong has a line earlier in the episode in which she mentions a son and daughter, which matches up with Lena and Lex, but Lena also has a birth mother out there somewhere, so we'll need to wait for confirmation. Regardless, we now know who she is, and it doesn't bode well for Lena, Kara, or living beings (both human and alien) in general.
