Clint not only knocked out Theresa and Brady, but took blood samples–at least from Brady. Maybe Clint is taking blood tests so that Kristen can switch them around at some point. That way, no one can prove that Theresa is the baby’s mother. Maybe Kristen will switch Theresa’s for hers. Now, I don’t know about why Clint took the blood test from Brady unless it was so that no one would know he is the father. After all, if Kristen gave birth to a child, I don’t think she could pass the child off as Brady’s since they didn’t have sex when she came back for the second time. Sorry this is so convoluted!
