CSI S09E05 “Leave Out All The Rest” IMDB Aired November 6, 2008
The discovery of a dead body (what else?) with the marks of S&M leads Grissom back to Heather Kessler.
In this case, it’s a set of markings from needle play around the man’s nipples, out of place next to all the corpse’s other injuries.
Grissom: “S and M?”
Willows: “Gone very, very wrong.”
ME: “These stab wounds are brutal, random and postmortem”,
Willows: “Which is inconsistent with S&M.”
ME: “Well, it’s hard to take pleasure in someone’s pain once they’re dead.”
Willows: “Which is the ‘gone wrong’ part.”
After the low point of the last episode, in which Heather was offering herself up to be murdered for money to provide for her grand-daughter, she’s somewhat recovered. No longer a dominatrix, she’s finished a Masters in psychology and is a practising therapist.
Heather’s transition to therapist from dominatrix who acts like a therapist makes a degree of sense. It’s consistent with the trope of pro-dominatrix-as-caregiver that turns up so often in mainstream media. (E.g. Going Under, Personal Services). It further desexualizes an already desexualized character. In this episode, Grissom is grieving his beakup with Sara Sidle, and his emotionally stunted interactions with Heather are with her as a caregiver, not a lover.
Also note that after being much more mobile and active in the previous two episodes, Heather reverts to being stationary in her home.
