I just realized how much Chuck resented Jimmy.

When Jimmy did all the ground work to build the Sandpiper case, it turned out it is a much bigger case for two lawyer to handle. Jimmy still wanted to do it with Chuck and was extremely against the idea of getting help. Chuck CONVINCED him to get help. Jimmy finally agreed and then Chuck CONVINCED him to get help from the person that Jimmy hates the most.. Howard.

Chuck could have asked a different firm for help which HHM eventually did anyways! Then this old fart goes behind Jimmy’s back and tells Howard to reject Jimmy and just accept the case.

Wow.. of course Slipping Chucky couldn’t resist the money, glamour, publicity, and success his firm would get from this case
