"Elementary" Season 3 spoilers in TV entertainment news reveals Sherlock Holmes (Jonny Lee Miller) gets a new apprentice and Joan Watson (Lucy Liu) has a new boyfriend. These updates are expected to affect the dynamic between the two main characters in the CBS series.

Spoiler alert: This feature contains spoilers on Elementary Season 2, and some updates on the new season. Read at your own risk.

Sherlock Holmes (Miller) gets himself involved with the British Intelligence MI6. Watson (Liu) moves out of Holmes' pad. Mycroft (Rhys Ifans) fakes his death. These are the developments in the Elementary Season 2 finale.

When the series returns on CBS later this year, Holmes will be "trying to get in Joan's good graces after almost a year away in London," TVLine reported, implying a possible year-long time jump in the Elementary Season 3 premiere.

Ophelia Lovibond joins the Elementary Season 3 cast as Kitty Winter, Sherlock's new apprentice. TVLine also reported Winter's relationship with Sherlock Holmes "will have ongoing repercussions for his relationship with Joan."

Lovibond also stars in Marvel's "Guardians of the Galaxy" as Carina. This film, which features Chris Pratt, Lee Pace and Zoe Saldana, debuts in U.S. theatres on Aug. 1.

Raza Jaffrey is also in for Elementary Season 3 as Watson's new boyfriend. It seems Mycroft's fake death effectively ends any further romance with Watson, at least for the time being.

Fans are eager to find out in Elementary Season 3 whatever Holmes finds in his MI6 stint, and how he would find his way back from London to New York (assuming Sherlock will be NYC-bound, after all). Captain Thomas Gregson (Aidan Quinn) and Detective Marcus Bell (Jon Michael Hill) are likely to play a role in Sherlock's return.

Will Sherlock Holmes backslide to substance addiction? Viewers saw Sherlock secure a packet of heroin from his secret stash, but it remains to be seen what he does with it. With new characters coming, Elementary Season 3 is hoped to bring some fresh twists and turns for its avid viewers.

The Elementary Season 3 premiere airs on CBS on Oct. 30, according to TVLine.
