As much as I'm not bothered about Zach, there's something refreshing about him being a different type of guy from the LI norm.
Molly totally reminds me of someone (not Ellie G or Kate W, though), and I just can't place who it is.
Mitchel is a much better version of Luca in both looks and character.
I have to say, I'm quite liking the mix of islanders so far.
Re the public vote for the first coupling, it's encouraging that they put the power in the hands of the public. Here's hoping they're planning on doing more of that throughout the series.
