What Mary and Chris didn't realize that the vials had ampped up their fertility so that after both had came in each other that they were at the most fertile time of the month.
Chris tells Mary that he wants to return to normal before he has to go to work but when they try to pull out another vial to return to normal it wouldn't allow them to take another out. Chris then noticed that there is a booklet setting next to the box with the vials and then picked it up and started to read it.
It says that there is only one way that the vials won't come out is if the person is pregnant and that they won't come out until after the baby is born.
Chris tell Mary what he found out. It also said that a month after you become pregnant that you body will transform into a perfect pregnant version of your body. Chris realizes that means that in a month he will become a full female.
Mary then says that what we can do is get a abortion so we don't have to have the kids. When Chris tells Mary that it says that if they try the abortion route that the vials won't every unlock.
