Last night's episode of The Mentalist (4x04- Ring Around The Rosie) gave us some little details about Lisbon's past. So I updated the Teresa Lisbon Profile with those details.
You can read them also if you click on Read More. It's spoiler of course, if you still havent' seen the episode. ;)
A new detail about Lisbon's past is that when she was in college, Lisbon used to love listening to the music of Willie Shubert, a saxophonist. She met the musician during investigations in episode 4x04, and Lisbon told him that whenever she felt sad because she missed her family in Chicago, she used to listen to his music and it used to help.
This also tells us that she didn't attend college in Chicago.
