Why?! Why would he send them home?? He said he was sparing the other girls embarrassment and/or broken hearts.
I call HOGWASH! Just like his buddies said, "He'll be all over them!"...Adam knew he would be too!
He knew that he'd be all over them just as much as he's been all over the original girls. He knows that it's part of the show to bring in "better looking" contestants to stir up the pot, and he is just trying to look as if he's the hero for telling them to leave. If you think about it, I think he did a disservice to the originals...he should have KEPT the new girls there and still continued to show interest in the originals. But he COULDN'T!
Also, if you think about it....if I was one of the original girls and I found out AFTER the show that he sent them home, I'd be offended! Because he basically said that I was NO COMPETITION to the new girls, and I would have been broken-hearted seeing them there!

Thanks alot pal.
I sure hope that the girls see in the promo's that he sent them home. Then, not only will they see him kissing everyone..they'll also see that he was LYING to them when they asked what he did that day. (he said he did nothing :rolleyes) Hopefully they'll understand that he didn't send those women home to be all cavaliering either....he was afraid of looking bad (by the viewers) by tonguing the new girls and probably picking one of them in the end.
