no and why the hell underage? if you want kiddie porn then you are at wrong place.
I'm surprised that this was only brought up now. I blame it on different time zones. As for the paternity of the eldest daughter:
I'm actually in this thread often enough and I don't recall anyone arithmetically disproving that Frank could not theoretically be the father of the certain person. As far as my memories don't lie to me, then it has merely been refuted, including by me, that it is very unlikely that the definite father of the younger of the two (Trevor is his name) ex-stepdaughters could also be the father of the older, because the potential window of opportunity is too narrow for that.
And while I don't insist that Frank has to be their father, I had theorized in the past that Shannon was so drunk off her ass at a girls' night out with the clique that she got hooked up by some guy who got her pregnant.
Otherwise, a small correction: The first time Frank and Shannon were together, they were only together for a year or so. When Frank and Shannon got married years later, Shannon, after getting pregnant with her youngest daughter, had her ovaries tied, to put it flippantly, so she couldn't get pregnant anymore. Therefore, it is definitely not due to Frank's fertility.
