Jane (Angie Harmon) will be facing a worthy adversary in the second half of the hit TNT series "Rizzoli & Isles" season 6.

During the midseason finale, Maura (Sasha Alexander) was kidnapped by the person who wanted her best friend dead. When Jane's apartment got razed, the perpetrator admitted to being hired by someone to do the deed. She died without divulging the name of Jane's nemesis, however, so their lead was gone. Things were going back to normal and everyone thought the killer has given up. Then came the bad news. Maura was missing and no one could tell where she could be.

When the series comes back in February, Jane will find herself still clueless on who abducted Maura. TV Guide reports, though, that fans should not be worried about the doctor's situation, as she would be freed in the end. What they and Jane should be concerned about is that the creative team of the series is cooking up an antagonist unlike the agent has ever encountered before. Executive producer Jan Nash shared about this interesting tidbit in his recent interview.

"There's a mysterious element to it. It takes a while to figure out what's going on. When they do figure out what's going on, it'll take a while to catch the perpetrator. We want to give her a meaningful nemesis in addition to these standalone episodes," he teased.

Nash also mentioned that Kent (Adam Sinclair) would still be around for the rest of the season. The executive producer previously told The Hollywood Reporter that he and Maura would be sharing a somewhat strange relationship. Could the lab assistant be his boss' kidnapper?

"We wanted to fill out Maura Isles' world, and have some more people who could be in her world, and we could see her as someone who manages people."

"Rizzoli and Isles" season 6 will return on Tuesday, Feb. 16, at 9 p.m. EST on TNT.
