Dean Cain's character, Jeremiah Danvers, returns to "Supergirl" this coming Monday. Teri Hatcher has already been confirmed to debut later this season in an as-yet unspecified villain role.

It doesn't take much to connect those dots, and arise at the natural question: Will "Supergirl" feature an on-screen reunion between Cain and Hatcher, who starred in "Lois & Clark: The New Adventures of Superman" from 1993 to 1997? During a Friday press event attended by CBR, "Supergirl" executive producer Andrew Kreisberg stopped short of confirming it, but did make it clear that he'd like it to happen.

"We'd love to," Kreisberg said of a Cain/Hatcher scene on "Supergirl." "There's a plan -- if we can execute the plan."

Hatcher is the latest example of legacy casting in a Greg Berlanti-produced, DC Comics-based TV series, in the tradition of John Wesley Shipp, star of 1990 TV series "The Flash," appearing on the current "Flash" show; and Lynda Carter, the iconic TV Wonder Woman of the 1970s, guest-starring as President Olivia Marsdin earlier this season on "Supergirl."

"In the best examples of the legacy casting that we do, whether it's John Wesley Shipp or Helen Slater, Lynda Carter, all of them, to a person, are so proud of the contribution that they made in the past and are so proud and happy to be part of our show moving forward," Kreisberg told reporters at The CW's Burbank offices. "And Teri [has] turned out to be the exact same way. She is in this for the fans, and knows what her being a part of this means to so many people. [Hatcher and Cain are] both really excited to give back."

Don't expect Hatcher's "Supergirl" role to be similar to her previous stint as Lois Lane, though -- or to resemble any of her earlier TV roles, as this one appears to be considerably nastier.

"What's so amazing is, she is so not playing Lois, and she is so not playing any character I've ever seen her play before," Kreisberg said. "She's so not Susan from 'Desperate Housewives.' She's really playing something completely different than what was in her repertoire of all the things that's she's ever done, and she's doing it amazingly. It's really exciting for us. Usually with some of these things, it's like, 'Oh, it's just a pale carbon copy,' or 'They're just repeating themselves.'"

"She can say one word, and then all of a sudden, the way that she says it, you're like, 'I don't want to cross her,'" "Supergirl" co-star Chyler Leigh added. "She's got a lot of power in that teeny-tiny little frame of hers."

Fans won't have to wait long to see Hatcher -- Kreisberg confirmed that Hatcher's character will be first seen in episode 15 of the show's currently unfolding second season, scheduled to air on March 6.

"Supergirl," starring Melissa Benoist in the title role, airs 8 p.m. Mondays on The CW.
