Well if he as that would mean he would havee to cheat on his wife (multipule times) and I think the What do it do ep explained it well.. there first (and only) date went bad.. I dont think a bad date has someone end up prego. And I think BOTH of them are better than that. And I genualy think Heinz is a good guy, I doubt he would of done anything with Linda and I HIGHLY doubt he would have done the dirty and just left her with the kids! (Good golly... this show is Y7!)
