Funnily enough, I had similar feelings when Henry Paul was brought in to accompany Robbie! I thought they were far too alike and unlikely to be a good 'foil' for each other but, to be fair, that worked out pretty well in the end. They were brothers, of course, which does bring a different dynamic, but both were [as so often with brothers] clearly very competitive with each other, so those similarities, hopefully, wouldn't be a problem this time either. Brothers in arms?
