Only six episodes into DC's Legends of Tomorrow, and there is already talk of adding (and maybe) removing some of the show's characters. This information is being provided by Joseph David-Jones who played Connor Hawke in one of the most recent episodes, says that it is likely we have not seen the last of him, due to the doomed timeline.
If you don't remember, the timeline was fractured and offers alternate futures meaning nothing is permanent so far. Which means it can still lead to other heroes joining and helping the team in their mission, like Hawke himself.
"I know that a couple of the writers are trying to push to get me back in there, because they really do like what happened with the episode, I know that they're trying to put me back in there but I don't know what they're going to come up with or what even is going to happen with Connor Hawke, but I know they've been talking about potential different outcomes of it because they are plan on cycling out some of the cast from the ship. So I don't know what's going to happen, or if that timeline is still set until they actually do go back to the past."
As you can see, he says that characters are going to be, "cycled out," which you can then largely takeaway that some people will be leaving, and most likely some new characters will be joining the team.
Perhaps the new members can consist of characters like Vixen, Connor Hawke, and a fan favorite, John Constantine.
'DC's Legends of Tomorrow' airs at 8 p.m. ET/PT, Thursdays on The CW.
