- Don abandoning Alice, and their later reunion, when she forgives him. Too bad it ends up with him being infected and then killing her. Also, on that same scene, Don trying to fight the infection as it takes over his body.
It doesn't help also that you're forced to watch Alice get beaten up by her husband..
- Alice's death is just so damn depressing: Abandoned by her husband for dead, becoming a carrier meaning she could have been vital to creating a cure for the Rage Virus, only to have a Hope Spot with reuniting and forgiving Don...and then getting beaten to death by her husband who she infected. Damn does the universe hate her.
