Something I just remembered which made me go hmmm:
A couple of weeks ago Sam was spotted making a secret trip to Sydney that he tried to hide by posting a picture suggesting he was spending the day in Melb. According to people at that Bachelor forum this has happened a few times (trying to hide trips to Sydney).
I still don't think it's going to be Lana that wins but remembering that made me go hmm, because unless the trip to Sydney was to meet up with the chosen girl why try to hide it?
Unless maybe the meet ups with Snez have actually been occurring around Syd so the ending wasn't given away if either of them were spotted to or from Perth/Melb?
And if it was Sarah why try and hide the trips to Sydney?
