It has now been proven that the kiss was filmed more than once (so they were asked to redo it for a different camera angle)
No wonder it seemed awkward and unnatural as they were made to repeat it.
And also explains why she felt it was a peck as on the lips (which the first kiss was) but he said he tried to kiss on the cheek (which he did the second time they were asked to do it)
At the end of the day it was a friendly kiss that didn't mean anything to either of them....but seemed to mean a lot to producers who orchestrated the whole drama around it and poor Laura.
Both jack & G have been accused and blamed and everyone is speculating over a non-issue....because producers have manipulated it. It seems unfair, but at the end of the day they knew they signed up for a game when they joined LI.
