Supergirl won’t be overshadowed by the return of Superman (Tyler Hoechlin) or the arrival of Zod (Mark Gibbon) in the season 2 finale.
The sophomore season of Supergirl not only marked a shift for the female-lead DC television show from CBS to The CW, it also brought new changes for the Kryptonian hero.
Like with any of these characters, no matter who it is, there’s been a Superman before us and they’ll be a Superman after us.
Everything, every character, no matter who it is, is there to service Supergirl and Kara.
