Beckett was injected with a drug at the end of the latest episode of Castle as she was whisked away. The show then cut to a scene in which Dr. Nieman received a call, in which a distorted voice told her it was "done." As Castle goes on the hunt for Beckett, he will have to contact Tyson and Nieman.

Castle show runner David Amann spoke to Entertainment Weekly this week about what it will take to find Beckett.

"The paramount goal is finding Beckett," Amann said. "But in order to do that, having access to Tyson and Kelly Nieman is a big part of that because the overwhelming suspicion is they're behind this disappearance, so being able to confront Tyson and Nieman are very much things that they're trying to do, in the service of finding Beckett."

Additionally, Castle fans will not learn much about Tyson and Nieman's past in terms of how they got to this point. Instead, some information about their future goals will be revealed.

"We will get a little bit of a sense of where they hope to be going moving forward in the next episode so it will be more about where they're headed as opposed to where they've been," Amann shared.

Castle airs Mondays at 10 p.m. ET/PT on ABC.
