okay... I'm going to say something I just realised.
Did u see all 3 pv's in a row? 'cause I just made it, I saw the 3 pv's on vimeo, on wide screen, and I really felt in love. At least till the last moment on the walk pv, when the waiter appears on the beach.
I think that it's a shame 'cause they could made an incredible conclusion. Walk is an amazing song, and the lyrics join perfectly with the meaning of the first two songs and the whole walk pv story. I mean, in the walk pv the sisters appears "happy" after all, 'cause that's the point, we have to keep walking even if things are not great, even if we don't know what we are going to find on the road.... it's sad for me, that the waiter appears, I think the whole concept of the story will be nicer without his final appearance.
I don't know if I explain my thoughts clearly... If not, sorry! my english is very poor and to me it's difficult express some things in a better way...
