"The Killing": Jamie Anne Allman talks "shocking" season 2

(CBS News) AMC's "The Killing" star Jamie Anne Allman, who plays murder victim Rosie Larsen's fun Aunt Terry, says fans will have another season filled with twists and turns that will keep them on the edge of their seat, yet again.

"There's been a lot of interesting and shocking things that are going to be coming out," the actress told CBSNews.com about the show's second season, which they have almost finished filming. "It's been pretty fun to act in, that's for sure."

In the season premiere, Terry is left to fill in for her sister Mitch (Michelle Forbes), who felt she needed to get away from her husband and their sons to deal with her grief of losing her daughter.

"She's always dreamed of having a family and has always wanted the kind of life that Mitch has. So when she is finally given the opportunity to fill Mitch's shoes, we are going to see if she can handle the burden or not," said Allman of her character. "We also see what boundaries she's going to cross for love and comfort, while she's in the middle of heartbreak."

It wasn't until the end of the first season that viewers were made aware of more of Terry's personal life - including the fact that she was enduring a heartbreak and that she was an escort, a plot line that even caught the actress off-guard.

"I didn't know that I was an escort until they told me, and I was like, 'oh okay,'" she said, acknowledging that many of the actors aren't given their full backstory, but instead are given clues.

Shock and surprise is something "The Killing" viewers are very familiar with - last year's season finale caused an uproar amongst fans who though that Rosie's killer was finally going to be identified.

"I knew it was going to be pretty shocking for people and frustrating, so it's pretty understandable," admitting at times that she was on the same emotional rollercoaster that fans were on.

While she did not reveal who the killer is, she did admit that being the killer wouldn't be the worst thing.

"I would love to be the killer, not because I want to be a murderer, but as an actor you are always wanting to find things to act," said Allman. "[Playing] the girl next door that's smiling all the time may be fun for some girls, but it's not for me."

When asked if fans will finally be satisfied by the end of this season, she responded, "One can only hope."

"The Killing" airs Sundays at 9 p.m. ET/PT on AMC.
