Still, that’s not to say that Lena will never be turned against Kara and Co. Her surviving family members are vehemently anti-alien, and she discovered earlier in Season 2 that Lex has caches of weapons designed to take down aliens hidden all over the world.
Despite the crimes of her mother and brother, Lena has pretty consistently been on the side of the good guys.
We even saw her holding her own in a game of chess against her brother in a flashback to their youths.
Deadline’s confirmation that Katie McGrath has been promoted to series regular for Season 3 means that we don’t have to fret about Lena possibly being killed off in the rest of Season 2.
