most missed characters.

[capefear]

as most posts here start out, i've been watching seasons one and two over the weekend [to prepare for it's return] & curiosity got the better of me.. what characters from the past two seasons, that haven't made an appearance this season, do you miss the most?
i'd say my vote lies with deputy [or not so much] leo and gia goodman.

EDIT: i'm editing my choices to include dean, michael cera's character from "Rapes Of Graff".
