This Asian dude is doing the peace sign that Jon was not familiar of. Instead, he does on eof his own signature gesture to show that he's happy to take a photo with this guy. He sincerely hopes he's not offended by doing this. He just had a rough day and well, this is what he gets paid for, sarcasm.
This British boy band was very happy to know their fans. And they get to know one even better. This girl is very lucky enough to be surrounded by those glorious boys, but even luckier to be wanted by The Wanted. It's not enough to have their photo taken, it's even much more to have their attention for it.
