Quote fromday01: Why don't Kyle and Summer take their own paternity test.
Because no one has a reason to question the results that Nick received? Obviously, if Nick didn't have to drop this bomb, he wouldn't have. He must believe it, or he wouldn't have finally come out with it. So, right now, people are shell shocked and not questioning a lot.
I was wonderinig why results like that were just left in an envelop on his doorstep where anyone could have gotten to them. I would think that Nick would have to least sign for them.
