"What about this rumour about you and Benji having a fallout and are no longer talking?"
"Where'd you hear that?"
Now let me just precursor this by saying I really think all this speculation is nonsense, we've had these same issues for the past 2 seasons and finished top 4, AND just like Robbie laughed, "It's March!"
But The way he answered that question, so defensively. From a body language and a rhetoric point of view, Robbie is pretty much admitting there is a rift and is just poorly deflecting by challenging Johns.
EDIT: Watching the video again, he's wiping his hands alot on his jeans when the Benji issue comes up (sweaty palms are an indication of lying/deception). Conversely, he doesn't give any tells when he answers the question about Sheens and the playing group, so it's clearly he is telling the truth with that issue.
I enjoyed the interview, based on Farah's responses. I was happy that Johns asking the questions, but didn't think it reflected on him well. He kept raising issues which had no solid evidence - rumour is this, people are saying that. Based on that, Johns couldn't do anything except move on when Farah answered, rather than digging deeper into each issue raised.
In regards to the body language, I took it as Farah feeling a bit uncomfortable with the questions. If someone attacks you, you react defensively. He quickly turned that around to give some pretty good answers.
