10 Family Guy Characters Killed Off For Good

After Brian breaks up with his long-term girlfriend, Jillian, she quickly finds another partner in Derek Wilcox, a mild-mannered man who seems outwardly to be superior to Brian in every way - which makes it all the more difficult for Brian to try and win her back.

Described as the "best man ever", Derek is smart, funny, has his life together, and, by Brian's exclamation of "OH COME ON!" in the urinals, is even implied to be pretty well hung...

To no-one's surprise, Jillian won't take Brian back, and the next we see of the couple is in the feature-length season nine game-changer, 'And Then There Were Fewer'. As two of many people invited to a dinner party at a remote mansion, Derek and Jillian are suddenly embroiled in a huge murder mystery when several of the guests end up dead.

When Derek runs up to the balcony in the hopes of picking up more signal on his phone, the murderer creeps up after him, to which he hilariously cries, "Oh my god, it's you! The man or woman who's been killing everyone!"

Inevitably, these end up being the man's last words, as Derek is smacked over the head with actor James Woods' Golden Globe award and thrown from the balcony to his death.
