Although Doug is really excited about working with Carrie, she isn't as thrilled with the idea. After Doug shows up to get prepped for the trial, Carrie is panicked that he is going to embarrass himself and her, so she tries to get Deacon to testify instead, which of course, hurts Doug's feelings. Pruzan is insistent that Doug be the witness, and after a lot of begging from Carrie, he agrees to come back and help her out.
