I liked this episode. Seeing the contrast in Patrick's behavior was a change that I enjoyed seeing.
I honestly forgot it was in Season 4, but this episode definitely stands out as a good one to me in Season 4. I liked the "subspecies" joke that I haven't seen too many people talk about, thought that was funny.
Also thought it was funny how he just became "too smart" for everyone. A change-up.
Ending was great.
8/10 episode!
