I know in season 4 Quinn steals money from a guy's safe while searching a crime scene then Dexter saw him and he wanted to talk to Dexter to see if they were cool and Dexter wouldn't snitch but every time he tried talking to Dexter he kept ignoring him so maybe it is one of the episodes in season 4

Its in season 4. Some episode after the 5th one.

Its when quin learns that dexter had kept his apartment even after moving in with Rita and gets suspicious of him and follows him around.

Finally he follows him to a bar, Dex notices and send a woman towards him, while he gets distracted, Dex flees B)

PS. I wouldn't call myself a dexter fan. Really loved the entire series apart from the ending. It ruined the series. Such a lovely show, such a fail ending.

You are looking at probably season 4 or 5. IMDB does synopsis breakdowns of each episode and there is a Dexter wiki.

I love Dexters Lab

Ok I was wondering does anybody now that episode of dexter when, Quinn is suspicious of dexter, and he waits at his car, and he tries to get dexter to stop to talk to dexter, but dexter pushes him down, if so what is the name of that episode
