In Italian, he says: "It’s official were here again. I told you there was going to be a second episode. We're here again.
"Later on I’ll tell you more about everything that happens.
Then: "After 1.5 hours at the airport we’re going back home.
"Well theres not much more to say, we’re going home, let's hope we find a solution.
"Were always positive, theres always a solution. Who knows?

"No I’m not going to, I’m going to keep it on all night," Diamanti replies.
"One thing is sure, I’m not going to unpack.
