Just reread all of the reasons why we hate Ruby because my sister forced me to rewatch the Sam and Ruby sex scene. (perverted witch...i'm so mad at her right now) but, to add on to the last reason...Ruby forced herself onto Sam!!
There's just so much that he can take and she exceeded the limit! What a b**ch! Ugh! I hate her...I hate her...I hate her!! Thank god she's gone!!
