Patrick just got arrested for spying on the Red John case files and Lisbon calls him stupid for that.
…
"Stupid?" responds Patrick. "Is that how you see it?"
"I—"
"I can't believe I how wrong I was about you. God, I feel so foolish. Here I was, thinking that you were the one who understood me, all the parts of me, and the one who truly 'got' me…all my actions and strange ways, my faces…I thought you really always understood everything about me …why I do the things I do…and most of all I thought you would always support me. That's what love is isn't it? … Well then, I guess that clears things up—you don't share the feeling. I'll keep that in mind."
"Patrick, I—"
"Goodbye, Teresa."
