Significance of Hewitt Watson

Watson is the insurance agent who sold Sweet the insurance on his new house. When he discovers a problem with the policy he meets with Sweet to correct the paperwork. The frightened Sweet tells him his story about the new house and asks him if he can find some men and come over that night to help them out in case there is trouble. Watson brings Morse and Washington. He is also arrested with them that night. Charges against Watson are dropped after Henry's acquittal.
