Life on Mars finally returns to the air tonight.

That's exciting enough.

But Zap2It's Korbi Ghosh also has this piece of news regarding two of the show's main characters:

Romance between Sam and Annie will definitely develop in the second half of the season. Of course, this doesn't mean Sam's 2008 girlfriend, Maya, will disappear.

According to Life on Mars Executive Producer, Josh Appelbaum, because Lisa Bonet just had a baby (and has been on maternity leave), viewers won't see Maya as much.

However, her character will return towards the end of the season... with intriguing information that may rock Sam's world.
