Supergirl just keeps getting better and better, and with only six episodes left of the second season, there's still a lot left to look forward to. After the hugely successful musical crossover episode with The Flash, we've got Kevin Smith returning as director for next week's 'Distant Sun', and a potential setup for the Kryptonian/Daxamite conflict to get a little bit bigger before the season's end. In addition, there are plenty of questions left to be answered this season - not just about Kara (Melissa Benoist) and her relationship with Mon-El (Chris Wood), but about CADMUS, the future of aliens on Earth, and how this might lead into season 3.
Now, we're starting to get the first hints at what might happen in the upcoming third season, with the news that at least one character is getting a boost to series regular.
Lena Luthor (played by Katie McGrath) will be returning in season 3 as a series regular, reports Deadline. The character first appeared at the start of season 2 on the show, and has been a recurring character this season, having appeared in seven episodes thus far.
Lena Luthor is the sister of Lex Luthor and the daughter to Lillian Luthor (Brenda Strong) on the show, and the head of L-Corp. She has been a friend to Kara for most of the show, with a dynamic that is reminiscent of the one between Lex Luthor (Michael Rosenbaum) and Clark Kent (Tom Welling) in Smallville. Although her mother heads up CADMUS and is very anti-alien, Lena is not part of the evil organization, and is attempting to distance herself and her company from the Luthor name.
We'll be interested to see what this bump means for the character - it would be fantastic to see the relationship between Kara and Lena develop further, and we would love to see Kara with a female friend (other than her sister, of course). This also means that the Luthor family and CADMUS are likely to continue to play a big part as the "villains" of the show, and we'll be happy to see that drawn out over several seasons, rather than wrapped up early on.
However, Supergirl already has quite a crowded cast of regular characters, and adding in more season regulars may make it difficult to really develop these characters or give them each enough attention to keep fans happy. Some may also wonder if this move will make the Lena/Kara relationship a little too similar to the Lex/Clark dynamic from Smallville. That said, we are excited to see more of McGrath on the show, and can't wait to see what season 3 brings.
Supergirl continues next Monday, March 27th with ‘Distant Sun’ at 8pm on The CW.
