If you are able to discern his motivations, you can probably have faith that others will, too. The extent to which your ego is bound up in taking credit, having a certain reputation among your colleagues, etc, is the exact extent to which your coworkers behavior can "get to you". Always the best advice is: do your job to the best of your ability and don't worry what anyone else is doing. Others will notice. And if they don't, then perhaps its not the kind of place you would want to work, anyways?
