Despite an earlier comment by CBS CEO Les Moonves that the network would renew all five of its freshman series, a lineup that includes "Supergirl," for the upcoming season, when the official renewal announcement was made, none of the five new shows were mentioned.

In a recent interview, "Supergirl" star David Harewood says that while he doesn't know much more than the fans at this point, he's optimistic about his chances to continue to explore his character in a second season.

"CBS has made some very positive noises," Harewood told Digital Spy. "All I know is that we've just had one of our biggest audiences of the year so far with the 'Flash' crossover, so it's all looking positive. The fans have been very vociferous and very vocal, so hopefully it's enough to get us a second season."

While "Supergirl" has maintained steady ratings over the course of the season, they never quite reached the heights of the series premiere. The "Flash" crossover episode helped boost the show's numbers, with the episode seeing a 31-percent boost over the previous week.

"Supergirl" airs on CBS on Mondays at 8 PM ET. The Season 1 finale arrives April 18.
