Fans of the acclaimed CBS TV series 'Criminal Minds' are very anxious to watch the 18^th episode of the 10^th season especially since the episode will be playing around politics, after a long time of not featuring a case that involves politicians.

On that note, reports have already come out releasing spoilers for the upcoming episode entitled 'Rock Creek Park'. The BAU will reportedly investigate a Congressman's missing wife and will be delving into the politician's possible political enemies which are definitely worth waiting around for.

Surely, reports claim that the upcoming episode, which will air on March 25, will have a puzzling effect for its viewers as it is obviously hard to find out how a person or a group of criminal-minded people orchestrate in taking the Congressman's wife if indeed she is kidnapped.

One whole week of not seeing the show might frustrate a few fans but the long wait will be worth it as the show will take in one of the veterans in the acting industry to intensify the upcoming episode. On that note, it has been confirmed that Academy Award-nominated actress Tess Harper will be featured in the episode.

Harper, known for her work in 'Crimes of the Heart' will take part in the politically-themed episode as Dinah Troy, the mother of the Congressman in search of his wife. Reports claim that Harper's character will give a little twist in the story, as the actress cannot be given just a supporting role, it is speculated that Harper, being the mother in the story may have a major contribution in the crime.

Also, Kate's character in the show, played by the pregnant Jennifer Love Hewitt will now reflect her pregnancy in the show. On that note, fans are excited about the recent announcement by the executive producer of the series

"She's been acting out a little bit, and we reveal it's because Kate is gonna have a baby," executive producer Erica Messer told TV Guide. And in the previous episode that started the pregnancy arc, she said, "The fact that she and Chris decide to have a baby rocks Meg a little bit."

Hewitt's pregnancy will have the interesting twist continue in the forgoing episodes. "Even though she's been raised by amazing people, there's an underlying abandonment since her parents were killed when she was very young. She's trying to deal with that and being 13 and navigate the world and see her place in it," Messer added.
