Season 6 of the detective drama, "Rizzoli and Isles" is preoccupied with Maura Isles (Sasha Alexander). Most episodes so far hint at the medical examiner's personal life. If she confronts her adoptive father Arthur Isles in one episode, she is looking for friendship in another.

This week's episode, "Sister Sister's" synopsis states that Maura will have a peculiar conversation with her ridiculously hot assistant, Kent Drake (Adam Sinclair). So far, the two share an odd relationship, and although Kent challenges Maura's patience, she will turn to him in "Sister Sister."

As reported by TV Guide, Maura and Kent's relationship will mature mid season and "there will be a nice story between them and we'll learn a little more about who he is and how he ended up in Boston."

Executive producer Jan Nash told TV Guide that there wouldn't be romance between the two. ""We wanted Maura to have someone else to bounce things off of [besides Jane]. We're not planning on an inter-office romance."

The question that begs to be asked is this: why does Kent feature in this episode at all? Does he have a hand in the murder that Jane (Angie Harmon) and Maura try to resolve in episode 10?

While the producers will focus on Maura and Kent, this week's episode will present a bizarre murder. The victim is a dog trainer, and the main suspect turns out to be her precious Rottweiler.

In the promo for Episode 10 "Sister Sister", we see a dead person's hand mutilated by what appears to be dog bites. Some characters in the show don't believe that the dog could have harmed its owner, but will their theory be proven right? The Rottweiler seems ferocious and even attacks someone towards the end of the promo clip.

Could that person be the killer? Furthermore, does Kent share a relationship with that person? After all, Maura wouldn't turn to her annoying assistant if he didn't possess any knowledge about the case.

'Rizzoli and Isles' airs on Tuesday, 18 August at 9pm on TNT. You can live stream the episode here.
