'Castle' Season 7 continues with Episode 3 entitled, "Clear and Present Danger," which airs October 13, on ABC. Beyond that, fans will be excited to learn that the network has released a promotional video for the episode.

According to the blurb below the promo, ABC producers write, "a pool shark is murdered by an unseen force, Castle and Beckett uncover evidence that the killer may have paranormal powers. Meanwhile, Castle and Beckett attempt to get their lives back to normal following his disappearance."

Evidently, it seems that "Caskett" will continue in their attempt to find out the truth behind Castle's disappearance in the Season 6 finale. As fans can recall, Rick's loss of memory prevents him from remembering any details about the possible kidnapping.

However, in a recent interview with TVLine, one of the actors on the show provided some insight into the disappearance and who might be behind it. TVLine spoke with 'Scandal' star Matt Letscher about his appearance on 'Castle'.

While he couldn't reveal too much about Season 7, he did mention quite a few interesting things. First off, he said that his character, the fake Henry Jenkins, has a history with Rick Castle and might be behind the ordeal.

Letscher said, "He definitely has a history with Castle. As far as I can tell, he is someone who looms large in Castle's past."

He went on to talk about Nathan Fillion's suggestion in an interview that the whole kidnapping thing isn't as "dark" as it seems. Letscher said, "He would know better than anybody, but I don't know.... Even on the set when we were shooting, they played both sides of the fence with me. I think that could be partially because they want to leave themselves some options."

Stepping into the latest episode, some of the fans of the show, via Reddit, posted their opinions of it in an official "Montreal" episode discussion thread.

On user wrote, "I actually liked this episode more than the premiere. I didn't like the whole "amnesia" storyline but now that we know he wanted to forget what happened, I'm actually intrigued."

Another wrote, "Wow, I really liked this episode. Went back to good old Castle. And I'm really liking the whole wanting to forget thing, its an interesting twist. Also I'm really glad they're gonna address why he became a mystery writer. Looks like we are in for an interesting ride guys!"

Evidently, even in the seventh season of the series, the viewer base is as prominent and eager to find out what happens next.
