It's funny. But I bet that is similar to how it went. Kim didn't give them up due to some master plan agreement... I think he would have been

The agreement to release the "hostages" was made well before Slick Willie came into the picture. His only job was to pick up two chicks and take
them home - something which he had done on at least one prior occasion (see wife).
