A peck on the cheek?

Now everybody knows that Tristan Caldwell and Sophie Mcabe 'like' each other (if you know what i mean-hehe) but how many people know about the little kiss they shared on the last week of term!
many good sources have comfirmed that it was more than a peck on the cheek (it was a nice snog!!!!) but still many people claim it was a quick kiss and Tristan claims it was hardly long enough to be a Peck on the cheek!
So was that little kiss in 6D a kiss or a way of saying goodbye for the summer, hopefully i will get more knowledge soon!
