"Castle" Season 7, Episode 2, titled "Montreal," airs Monday night on ABC. Fans hope to find more answers as to what happened to Nathan Fillion's Rick Castle for two months. Stana Katic tweets a "possible answer" for the fans.

This is what Stana Katic tweeted, teasing the events in Castle Season 7: "What happened to #Castle? Is he who he says he is? This man may have the answers (RoganDidIt)." It may have been a joke, though.

On IMDB.com, there is only one Castle episode listed in the profile of Eddie McClintock - "For Better or Worse." Still, McClintock retweeted Stana's message. (See the tweet here.)

"As far as I can tell, he is someone who looms large in Castle's past," Matt Letscher ("Scandal") told TVLine in an interview.

TVLine's Matt Webb Mitovich tells Letscher he's "afraid for [Henry] if Kate (Stana Katic) ever gets her hands on him again." The actor replies, "It could go really badly."

"As the rest of [NYPD] looks into the death of a toy company's CEO, Castle starts his own investigation after finding a lead in his mysterious disappearance," reads the episode synopsis of Castle Season 7, Episode 2.

In this week's new episode, Castle engages the public to supposedly find answers on what has happened to him in the past two months. As this develops, Beckett and Castle will adjust to their lives post-disappearance. There are relationship issues, but creator Andrew W. Marlowe and new show boss David Amann have earlier hinted fans need not worry about the Caskett ship.

There still remains some doubt on Castle, especially since he was seen in a video clip, dumping money to the men involved in his disappearance.

Matt Letscher is appearing in Castle Season 7, Episode 2, according to the actor's list on TV.com. It remains to be seen whether NYPD will get some more information from Letscher's Henry Jenkins.

"Are you ready to hear the truth?" says a man's voice on the phone. From the Castle 7x2 promo clip, it does seem that Rick Castle does not know what really happened to him. Then again, there remains more questions than answers at this point.

With regards to Stana's tweet, here's a reply from one of her followers:

"I never know if you're serious or just trying to troll us but oh well," tweets @shadesofcaskett.
