I heard that some of the spoiler sites are saying Sean picks Catherine in the end. I like her and they do seem to have great chemistry together but - after hearing her sisters' remarks - perhaps she and Sean don't end up getting married because she does seem awfully independent and like she is just giving things a try - not necessarily making a full commitment.
I am glad Tierra was finally sent packing - what a looney tune!
I personally think the best match would be Lindsey or AshLee - they both seem to be ready for marriage and the commitment that entails - and I guess I slightly favor Lindsey because of her military connection
