Being a former social worker, more than likely, she's requested child support and he claimed he was not the father or wanted to be sure so thus...the paternity testing. That kid is close to 2 years old if I remember correctly, has Rush's last name(which I know doesn't mean much). So basically, he probably hasn't been paying child support since the kids' birth thus...deadbeat dad...also, if he had questions about paternity, you hope he'd would've been smart enough to question it right after the kid was born.
