In Extinction, the mutated Dr.Isaacs had his curb stomp battle with Alice, and finished his "I, am, the FUTURE!!" speech. The incoming ham and cheese was quickly received with mocking laughter, followed by Alice's "No... you're just... anotherasshole."
Also in Extinction, Carlos's Dying Moment of Awesome was indeed quite awesome, he drove a gas tank into a horde of zombies with a bag of dynamites. As the truck crashed and he was about the light the fuse, he found half a cigarette, hidden by L.J.. Carlos finished the cigarette in one breath, and calmly blew the smoke out, as he watched the zombies crawl toward his truck and waited for the dynamite to go.
