Check out the Criminal Minds Season 10 Episode 1 Recap here.

With "Criminal Minds" Season 10 is finally upon fans, new cast member Jennifer Love Hewitt spills a few beans on her character, Kate Callahan. One word that she uses to describe the character is "interesting" because it seems that, with Kate, you don't really get what you see-there's something lurking underneath.

Hewitt is playing the role after a break from her stint in "Ghost Whisperer" and it seems that in the show, her role as Kate will see her spending time with BAU team lead David Rossi (David Mantegna) and Aaron Hotchner (Thomas Gibson), reports Entertainment Weekly.

Hewitt is not the only one that's getting some fans hyped up leading into the new season. TV Guide has managed to get the latest scoop on "Criminal Minds" Season 10. According to the source, Derek Morgan, played by Shemar Moore in the show, is going to see his relationship with girlfriend Savannah, well into the 10th season.

But he's not the only one with a thriving love life. Rossi will also have one episode that will hail back to his second wife, though showrunner Erica Messer has not provided any more details. As far as Rossi is concerned, there will be more episodes that will delve into his personal life, so that's a good thing to expect for "Criminal Minds" Season 10.

Even before the cast and the fans get into the groove of the 10th season of "Criminal Minds," Messer has already teased that this will see the return of one of the bigger villains that will hover over the heads of the BAU team-meaning a season-long unsub in the form of The Replicator.

Heavy reports that the premiere episode will already bring up The Replicator. And the showrunner may be planning some serious plot twists, given that the finale is already planned out this early in the production.

"The unsub for the premiere episode is only part of the puzzle. It will culminate in the finale. We know pretty much how Part 1 [of the finale] would end and how the finale would end," Messer said as quoted by Heavy.

Each of the characters may getting a good focus for "Criminal Minds" Season 10. TV Guide has compiled a list of teasers that will be coming in with the show. Resident tech geek Garcia (Kristen Vangsness) will still have some after-event trauma from the shooting in last season's finale, so a little PTSD and recovery should be expected.

Dr. Reid Spencer's (Matthew Gray Gubler) mom, Diana, who is played by Jane Lynch, may be making a comeback. And good news for Reid fans who have had enough drama and death-scare for their favorite BAU genius would be happy to know that the possible reunion between Spencer and his mom will not be a heartbreaking one. Perhaps this is to make up not only for Reid losing a girlfriend, but also almost being shot to death.

Lastly, fans may be seeing old faces coming back one more time the last 200th episode. Emily Prentiss or even Blake fans may be rejoice for another possible reunion. "I can't talk about it yet, but I've got an idea. It's going to be a giant team episode because those are my favorite," Messer said to TV Guide.
