The Mentalist is down to one episode before Season 6 concludes this Sunday on CBS. Fans have long been waiting for the moment where Patrick Jane and Teresa Lisbon are finally together, but with Agent Pike acting as the other love interest, Robin Tunney's character will have difficulty choosing.

Will Jane kneel and propose to Lisbon or are they going to agree on closure and move on different lives?

Executive Producer Bruno Heller revealed that Blue Bird is going to be the romantic finale everyone is waiting for.

"It's a romantic finale rather than a [suspenseful] finale. With the death of Red John, there's a sense of tying [things] up and certainly this romantic angle is one of them," TV Guide reported.

Rumor has it that Jane might kiss Lisbon before her departure to Washington with Agent Pike. However, the bigger question is: Does the kiss signify his wedding proposal or is it a parting message that they already have the closure they needed?

According to CBS, "In the sixth-season finale, a new lead in a cold case surfaces, forcing Lisbon to postpone her plans to relocate, and this delay allows Jane to examine his feelings for her and decide how to proceed."

Jane and Lisbon has a long history of brother-sister-almost-lovers relationship, so taking it to a higher notch would be difficult for both of them.

"It left the two of them without an excuse to decide where that relationship was going. They had always been able to keep it separate. Those questions start bubbling up and the rest of the season was the resolution of those questions," Heller told The Hollywood Reporter.

The Mentalist season finale airs on May 18, 10 p.m.. Live streaming is also available on CBS website.
