Well something happen just what we will probably never know. It would appear (from the footage) that they left the Sanctuary and headed straight to the kitchen where Jason fill them in on the spa-a-rama drama. They both have gone immediately into damage control - deny, deny, deny. Would have been interesting to see what if anything was said between the two before they went back to the BB House - if they came up with a story if questioned about anything happening because those two are too much on the same page and they both look guilty when someone ask if they even kissed. Lawson and Cat are using the George Costanza defence - "Jerry, just remember, it's not a lie if you believe it".
