The actor recently joined the show as Jake, the brother of late witch Nick (Louis Hunter).
Zylka has now told E! Online that Jake will continue to work with the witches at the moment.
He explained that Jake's relationship with Isaac (JR Bourne) will have a lot to do with his decision.
Zylka said: "The way I care and that Isaac cares for me... It really is going to be sort of the middle ground of what is going to happen, what choices he is going to make, and it plays off better and better with the witch hunters in every episode."
The Secret Circle, which has won a full season order, airs on Thursdays at 9/8c on The CW in the US and on Wednesdays at 8pm on Sky Living in the UK.
