There are just eleven women left, and if you thought things were serious before, Chris Harrison has some news for you: things are about to get EVEN MORE SERIOUSER, seriously. Also, EVERYTHING IS ABOUT TO CHANGE, because they're leaving Los Angeles, he tells them, and they get all excited even though they have no idea what's going to happen. Brad has already left Los Angeles, Harrison tells us, and half of the women are excited about THAT for some reason, and the other half gasp like Harrison said Brad DIED for god's sake. These women have the attention span of particularly dense squirrels.
There's lots of shaky travel footage as the women go to Vegas, and they are all excited, which makes sense, because when you think "lifelong commitment to your romantic partner" you think Las Vegas.
