Graham smokes while Jack Crawford tells him, that the tool used on the Jacobis' tree was a common bolt cutter.
The Greek god Hermes, whom Hannibal Lecktor represents, was considered to be a psychopomp. Psychopomps (from the Greek word ψυχοπομπός (psychopompos), literally meaning the "guide of souls") are creatures, spirits, angels, or deities in many religions whose responsibility is to escort newly-deceased souls to the afterlife.
In Jungian psychology, the psychopomp is a mediator between the unconscious and conscious realms.[a] Hannibal Lecktor acts as a mediator between these two components of Will Graham's psyche; at various places in the movie, ideas seem to 'emerge' from Will's unconscious into his conscious mind. For example, upon seeing the severed branch in the tree in the Jacobis' back yard, Will's unconscious 'knew' that the instrument used to cut it was also intended to be used to break into the Jacobis' house, but he did not consciously recognize this fact until later, while going over the Jacobis' home movies with Crawford. An intervening event occurred in which Crawford told Will that the tool used to sever the branch was a common bolt cutter. This piece of information, coupled with the initial 'recognition' upon seeing the branch, came together in Will's mind upon viewing the home movies. Graham was smoking at the point when Crawford relayed the important information to him (i.e., about the tool being a bolt cutter), and as discussed in part 64 of the analysis, smoking indicates the 'presence' of Lecktor/Hermes. The point is that here, Lecktor was acting as Will's psychopomp.
