There are plenty of under-2-hr flights between KC and Philly. That's not going to be THAT big a factor immediately. And I think that Aaron may have already called Gwen. Were I he, I would call her - and let Helene know that I did. He seems to be an honest guy - if there IS to be a marriage arising from this show, he'll want it to be right.
Remember, the producers had planned to purchase the engagement ring, but Aaron insisted on paying for it himself. Harry Winston does not give away rings like that one. And Harry Winston doesn't sell Diamonique.
