"Supergirl" Season 1 has no new episode this week on its home network CBS to give way for the 2016 Grammy Awards. Fans who would like to see how the "Supergirl" cast is doing are getting updates from the social media. Melissa Benoist and her husband Blake Jenner (who recently appeared in the show) appear to be on an extended Valentine's date. Chyler Leigh, meanwhile, says she is proud of their adaptation of the DC Comics series.

Spoiler alert: This update contains "Supergirl" spoilers. Read on to find out the latest developments in the lives of Kara Danvers (Benoist) and Alex Danvers (Leigh).

Without disclosing their location, Benoist shared on Twitter and Instagram how happy she is with her husband on their date. Prior to that, the actress retweeted a "twofie" photo posted by "The Flash" actor Grant Gustin, who is also a "Glee" alum like her. The photo shows the DC Comics emblems of Supergirl and The Flash. The crossover episode featuring the superheroes have recently been confirmed and announced. See the Instagram photo below.

For her part, Leigh shared a behind-the-scenes photo of Supergirl and a young Kal-el in Krypton. The still image aired a week ago. The "Grey's Anatomy" alum is obviously happy with the "Supergirl" cast and crew. She gave them all a grateful shout-out in her latest Twitter post. See the posts below.

In its Feb. 8 episode (Supergirl 1x13, "For The Girl Who Has Everything"), Supergirl's aunt Astra (Laura Benanti) dies in the hands of Alex. J'onn J'onzz a.k.a. Hank Henshaw (David Harewood) decides it is best if Kara doesn't learn of how her aunt died. This secret is expected to blow up once it is revealed. Hank reasons it is best if Alex stays as Kara's hero, instead of a DEO warrior who had to kill the enemy. In next week's episode, they face another DC Comics villain, Master Jailer (Jeff Branson).

"Supergirl does battle with the deadly Master Jailer (Jeff Branson), who is hunting and executing escaped Fort Rozz prisoners. Also, Cat hires a second assistant, Siobhan Smythe (Italia Ricci), who immediately tries to one-up Kara, and Kara and James disagree over the DEO's methods," reads the "Supergirl" Episode 14 synopsis from CBS. This episode will air on Feb. 22.

Variety describes Ricci's role, revealing she becomes a "deadly foe" eventually. In DC Comics, Silver Banshee is a known Superman villain, but she also fights Supergirl and Martian Manhunter. In real life, Ricci is engaged to Firestorm actor Robbie Amell, cousin of another superhero actor, Stephen Amell. The Amells have both appeared in "The Flash." Stephen is the central character in The CW's "Arrow," which served as the launching pad for "The Flash" and "Legends of Tomorrow" -- both from The CW. "Supergirl" is from CBS, the parent network of The CW. These shows are giving superhero fans a lot to watch and discuss today. Greg Berlanti's Berlanti Productions run these shows.

Cat Grant (Calista Flockhart) is the one who brings Ricci's Silver Banshee in Supergirl's grid. Cat and Kara were just beginning to expand their relationship beyond work when Kara realised she has to break-up with Cat's son, Adam (Jenner). Cat insists she can be professional, but she is unhappy over the foiled romance. Still, she appears to have a genuine concern for Kara's welfare, so fans can look forward to more conflicts now that Silver Banshee is added in the picture.

"Supergirl" airs on CBS every Monday. A complete season has been ordered, which bodes well for a second season.
