When CBS announced 18 renewals earlier this year, The Mentalist was not on the list.

So when this drama wraps up its sixth season next month, it may be wrapping up for good.

Has creator Bruno Heller penned an episode worthy of a series finale? Or will fans be left hanging off a cliff... forever?

"It's a romantic finale," Heller teases to TV Guide of what's in store, dropping the following bomb:

Pike will propose to Lisbon!!!

Heller would not reveal how Jane reacts to this development, but does promise closure for fans of the long-running hit.

"With the death of Red John, there's a sense of tying [things] up and certainly this romantic angle is one of them," he says.

Do you want to see The Mentalist Season 6 conclude with Lisbon engaged to Pike? Sound off now!
