Let's not forget he slapped her ass and told her to scream too. I felt Priya's apology was more sincere, where as Sam tried to turn it on others like Travis.
priyas apology was that she didn't stop sam, when she was doing it too. They didn't know it was upsetting her, even she didn't know why it was upsetting her. He slapped skyes bum in the spa, he patted Sandra's bum, he does that apparently! Not to say it's ok If Aisha isn't comfortable with it, but even she doesn't think they wanted to hurt her. Priya was not more sincere, she just didn't cop the blame like sam did and was able to say it straight away, unlike sam who was approached by trav first. Which caused other issues.
