Is Parrish Really Isaac's Brother On 'Teen Wolf'? Ryan Kelley Addresses Camden Lahey Rumors

Now heading into season 5, the MTV drama received an extra-large 20-episode order for their fifth year - a good sign that the series is in line for a season 6 extension.

"I think there's a good shot of [having a sixth season]," said actor Ian Bohen, according to MyFanBase. "I know that people are already talking about it at the network so we'll have to wait and see on that but I think there are definitely conversations about going beyond season 5."

The addition of Dylan Sprayberry and Khylin Rhambo injected some young blood into the series in season 4, and Bohen believes the youngsters add a new energy to the show - and there is always the possibility that the new generation could take over when/if Beacon Hill's elder wolves head off to college.

"The young cast that's coming in now, Dylan Sprayberry and Khylin Rhambo, they're great," Bohen explained. "It's so amazing to me, you know Dylan Sprayberry came out to surf with me a couple of weeks ago and he's such a good kid and he's a kid! I mean he's 16 years old and you forget the energy and the dynamics and the mindset of a real 16 year old. It's just beautiful! It's limitless energy and just a whole different kettle of fish. I think that they're a great addition to the show."
