Dwight has always been a loyal employee to Dunder Mifflin and someone who really admires Michael. Michael has not always treated Dwight with much respect. It's kind of similar to Michael's realtionship with Ryan except that Michael doesn't treat Dwight as bad as Ryan treats Michael. There have been cracks in the realtionship between Dwight and Michael this season but this time it really gets tested. Michael starts his own company and gets Dwight to help him out on potential clients. Dwight doesn't seem to have a problem with this until Charles praises Dwight for his work. Dwight has trouble in who he should be loyal to. When Dwight realizes that Michael is taking advantage of him he decides to go to "war" with him. Their competition in trying to land the client was pretty entertaining. You get to see how both are good salesman in their own ways. It's funny how Dwight tries to be casually interested in the clients personal lives.
Meanwhile Andy tries to help Jim with what he thinks is a problem that Pam is controlling Jim. This leads to an extended prank Jim pulls on Andy. This was pretty good to see. I like when pranks are extended like this.
This was a good episode that would set up things in future episodes.
