Lisbon went back home to the people who loved her…or hated her, depending upon your point of view, in The Mentalist Season 7 Episode 7.
There was definitely one person who loved her and that was Patrick Jane. When Lisbon's brother Jimmy ended up with a warrant out for his arrest, Lisbon slipped into protective big sister-mode and ran to his rescue with Jane by her side.
Patrick Jane: You know I could come with you if you wanted me to.
Teresa Lisbon: That wouldn't be any fun for you.
Patrick Jane: Fun's overrated.
