The entire premise of the finale is flawed. In a previous episode a character is convicted after confessing to Bull, and Bull remarks "oh, I'm not an attorney." (I'm fuzzy on exact details.) But this episode revolves around the client confessing to Bull and somehow his confession now being privileged even though Bull still isn't an attorney and the confession unrelated to the current case wouldn't fit the definition of privileged anyway. Total garbage and a sad way to end a show that has often relied on Bull being the SMART GUY who isn't an attorney.
