The 100 season four will have yet another new character! Bradley Stryker, who had appeared on other CW shows, (IZombie, Smallville, SuperNatural), has been confirmed to portray a character by the name of Baylis.
Baylis will appear in the soon-to-be-named seventh episode, along with Ilan, played by guest star Chai Romruen. Despite my best efforts of research on Baylis, I did not find out anything about his character. He could be a Sky person, Grounder, or Azgeda, but we will have to see when the new season debuts in early 2017.
However, I am guessing that Baylis might be Skaikru, but this show is certainly filled with Easter eggs and surprises. And, that is not a bad thing. A lot of the times it is sad.
Season four is currently in production in Vancouver, all behind-the-scenes stuff is deeply secreted as a standard rule. But, the good news is that it is worth waiting for.
