Spoiler alert! Ragers get into a private home that is owned by an elderly couple. The couple allows strangers who are also survivors to stay with them during the rage virus outbreak. A little boy comes to the house banging and pleading to be let in, but some in the group prefer not to open the door. Eventually the boy is let in, but he had ragers who chased him to the house. Well, things escalate, and the survivors are quickly taken down.
Don and his wife, Alice, run upstairs. The little boy is up there as well. Alice is so bent on protecting the boy (since she doesn't know where her own children are) that she risks her life after her husband pleads with her to come with him. And...well, you'll see when you watch this clip. I don't blame Don at all for what he did. And honestly, it tickled me.
