Although it was reluctant to deliver on the tagline heard throughout its inaugural season, the producers of The Killing want to assure viewers that they will unequivocally know the answer to ‘Who killed Rosie Larsen?’ But the second season has more up its sleeve than answering the many questions left hanging at the end of season 1.

As production on season 2 of the Seattle-set drama begins this week, showrunner Veena Sud is quick to set the record straight in regards to what season 2 has in store. Sud states, “We will solve the investigation of who murdered Rosie Larsen — all will be revealed — and there will also be a second case that emerges.”

While Sud doesn’t go into detail on how the Larsen murder and this new case will share screen time, it is worth noting that Michelle Forbes, who played Rosie’s mother, Mitch Larsen, to critical acclaim and an Emmy nod, has been brought back as a series regular. This seems to suggest that there are enough questions still surrounding last season’s case to take up the bulk of season 2.

With the implication being that Det. Sarah Linden (Mireille Enos) was duped into nabbing Seattle mayoral candidate Darren Richmond (Billy Campbell) for Rosie’s murder – at least partially by her new partner Det. Stephen Holder (Joel Kinnaman) – the ramifications that accompany such answers will undoubtedly be far reaching.

Also pressing is how the Larsen resolution, and additional case, will further disrupt Det. Linden’s personal life, which includes her somewhat uprooted son Jack (Liam James), and long-suffering fiancée Rick Felder (Callum Keith Rennie).

In addition, leaving things open for Forbes’ return, The Killing will also be bringing in two new major characters – though it is anyone’s guess as to how either will fit into one, or both, of the show’s cases.

For starters, Det. Linden will be receiving some much-needed help from Lt. Carlson, who is described as a dapper, well-groomed man in his fifties, who always has his finger on the proverbial pulse of Seattle’s political landscape.

With the high-stakes political arena playing such a large role in season 1, it should be to law enforcement’s benefit that a politically savvy individual is amongst its ranks – provided Lt. Carlson’s interest in purely from a lawman’s point of view.

Secondly, The Killing will introduce Alexi, a young Polish-American riddled with piercings and tattoos. This product of the foster care system is said to be a “dark, frightening teen who can turn on a dime emotionally.” While Alexi may sound like a prototype of misguided youth, his connection to either Rosie’s murder or another may make him a central figure of season 2.

Even though The Killing caught a bit of bad press with its inconclusive season finale, the program as a whole delivered a well-crafted, compelling piece of drama that garnered a handful of Emmy nominations (six to be exact), and likely has as many fans eager for its return as there are those skeptical of what the next season is promising.

The Killing will return to AMC sometime in the spring of 2012.
