French magazine "Télé Loisirs" published a short interview with Simon Baker, in which he talks also about Jane and Lisbon (Robin's character) relationship. I translated that part in english:
Simon Baker: "Romance with Patrick Jane? It is possible..."
During last season (season 2), your character apparead more relaxed, ready for a date. Are those days over?
In the moment that he feels like he can be human again, he's going to lose his bearings. Season 3 shows really how much Lisbon plays an important role in his life, as a colleague but also as a friend.
Is this friendship going to evolve in romance?
I don't reject this possibility. The relationship between Jane and Lisbon is more complex than the other relationships on television. Jane-Lisbon duo is a deep friendship story. People who watch the show don't fantasize to see Jane and Lisbon make love on the back seat of a car... Maybe you, French viewers! [laughs]
