Who is yin in psych?

Answer 1

If you mean in the season finale of "psych" then there are a couple of possibility's. One is that it is Shawn's mom, which is the best answer. Shawn's mom is the only one who could have known where Shawn and Abigales first date was going to be; She is also the only one who could have put the car bomb in her car in the episode "An evening with Mr. Yang."

the only problem with this is that yin is clearly a white male so it cant be his mom. you can clearly see this at the end of the episode when yin removes his fedora. (look at his hand)

Answer 2

well if you watched the season 5 finale on dec.22,2010 you would have seen them catch him and his new yang partner [mena suvaria] he is a principal at an academy he is not in Shawn's past at all like how yang lived 3 blocks down when Shawn was a kid you should have seen it the old yang is yin's daughter and get this she wants to come back home so she hugs him and stabs him with the poison he was going to put in Shawn and Gus

Answer 3

In Season 3, Episode 16, a serial killer named Mr. Yang challenges Shawn to stop him from killing a girl he kidnapped. Shawn apprehends Yang.

In Season 4, Episode 16, it turns out that Yang had a partner, who calls himself Yin. Yin challenges Shawn again, but is not captured.

In Season 5, Episode 17, Yin returns for a final showdown against Shawn, and tries to take revenge for his partner Yang's capture.
