I have sympathy for Sam that the eye incident happened. I'm not a fan of certain pranks as they easily tread the line between joking and bullying - and in this particular case it sounded like it went very wrong. However, Bear is very aware that a prank like that wouldn't go down well with Sam as she's very competitive. So it sounds like he was deliberately being antagonistic. Of course, because BB decided we didn't need to see it means we can't judge it properly.
But on the otherhand, I agree about Sam. I'm no fan of Bear but her interview was cringeworthy. She went on a rambling tangent and in doing so made herself look like a sore loser again. And her comments on BOTS about how the Americans shouldn't win as it's a British show were awkward to say the least...
