Like I said in my original theory, she probably didn't want to go that route, she probably just wanted him to pay for the medical bill originally since she doesn't have insurance, but the moment she went to a lawyer all that changed, because a lawyer is not about to sue an NFL superstar for a medical bill. He will try however he can to come up with something to sue him for more.
But why go the domestic violence route? Can't she just file a civil suit over negligence or something? From what I understand, it seems that Randy is guilty of injuring her finger or whatever, so she would get some money that way. If she realizes he's not going to pay up when she threatens him, why file a TRO, instead of filing a claim?
