Hopefully you’ve had enough time to digest Lost‘s Season 4 finale, because we now have more info to throw into the mix. According to Entertainment Weekly, two new characters will be introduced next year. And like many of the players we’ve seen over the years, these two won’t be leaving anytime soon. In fact, these recurring actors will be optioned for possible Season 6 appearances.

So what should we know about these two new entries? Well, as expected, both are being described as intelligent and dangerous. The male, Caesar, reportedly has a “dark past” and is “as skillful at charming people as he is at killing them.” Meanwhile, Ilanna is an “alluring” European female who is “used to getting her own way.” Neither role has yet been cast.

Lost - which doesn’t return until sometime after the new year - resumes production later this month.

On a side note: You can see the producers (Damon Lindelof and Carlton Cuse) addressing the fans of Comic-Con here.
