Abigail Lytar is a fictional character on the American television dramedy Psych played by American actress Rachael Leigh Cook.
Abigail Lytar is a kindergarten teacher and also the high school crush of Shawn Spencer. In the episode "Murder? … Anyone? … Anyone? … Bueller?", Shawn and Abigail met up at their high school reunion, but did
n't actually get back together until the episode "An Evening With Mr. Yang".
They dated for almost a year before she decided to take a trip to Uganda for six months, essentially making Shawn "single" ("You Can't Handle This Episode").
In the episode "Mr. Yin Presents ...", Abigail returns from her trip only to be kidnapped by Mr. Yin, and after nearly dying, she decides that she can't be with Shawn, unless he stops chasing psychopaths.
