Grey's Anatomy, Season 6Edit
There is no reference to Charles' family. When Percy is shot in 'Sanctuary ' he does not speak of his family or tell Miranda Bailey (in 'Death And All His Friends ') to give anyone a message. He only tells her to relay to Reed Adamson (who was the first victim of the shooter, unbeknownst to Percy) that he has always had a crush on her.
Percy tells Izzie Stevens that he has a crush on Reed, another Surgical Resident from Mercy West, and had so for a long time. When he is dying in 'Death And All His Friends ', he tells Bailey that she never knew about his crush, but Mary Portman reassures him that she did know because 'girls always know'.
When the merger first occurs between Seattle Grace and Mercy West Percy forms a quick positive relationship to Izzie Stevens. However he later shows that this is simply to get on her good side, as he talks negatively about her behind her back.
Percy is known for ironically saying in an earlier episode 'just shoot me now' (and later dies from a GSW to the chest)
