^That could be one of the pit falls of screwing over your team mate, when you've been told to hold station. If you need them later in the season to keep a title rival behind them, it would be very easy for them to go to wide on a corner and let your rival through. Webber doesn't appear to be a driver that would do that however.
I don't know; he looked more distraught than I've seen him before, so he may finally have snapped in that regard. In any event, it's probably been a blessing that they've had a few weeks between races to let everything cool down a bit.
It'll be interesting to see how things play out in China this weekend.
