From episode 1 my initial guess on the murderer's identity was the Headless Horseman. Upon completing episode 2 I feel my theory has been proven half-correct.
By the end of episode 2 we know from several scenes that Ichabod Crane held sexual if not more emotionally intimate feelings towards Snow White despite his outbursts of anger towards her. His constant belittlement towards Snow is due to symptoms of depression. Feelings of worthlessness are expressed in several ways, one being lashing out towards others which he is shown to do in both episodes. This feeling of worthlessness has made him seek out a way to feel more powerful, this is shown through the way he is violent almost bordering on rape during sex.
All these are symptoms of depression indeed, however the depression is only a symptom itself.
Ichabod Crane suffers from a severe case of Dissociative Identity Disorder, also known as Multiple Personality Disorder. An extremely rare mental disorder characterized by at least two distinct and relatively enduring identities or dissociated personality states that alternately control a person's behavior, and is accompanied by memory impairment for important information not explained by ordinary forgetfulness. (http://en.wikipedia.org/wiki/Dissociative_identity_disorder) However, I do believe Crane knows of his disorder and actively attempts to hide it from the others. I also believe that at times his alternate personality influences the base personality of Crane, mainly during times of stress.
The clues leading me to this conclusion are as follows:
- Looking at the out of game Book of Fables, several characters are shown to have different entries. These entries show other sides of the character.
Bigby has three separate entries in the Book of Fables.
- Bigby Wolf
- Bigby's Mercy
- Bigby's Vengeance
These entries correlate with the title of the page; Bigby's Mercy sharing a story of kindness while Bigby's Vengeance shares a story of betrayal and revenge. Other notable differences are the more human portrait in Bigby's Mercy and the more wolf-like portrait in Bigby's Vengeance.
Bluebeard has multiple entries as well, one depicting Bluebeard's base personality and story while the other depicts his mercy.
- Bluebeard's Mercy
Again, these entries correlate with the page titles; Bluebeard's Mercy shows a softer looking Bluebeard.
And now on to the star of the show; Ichabod Crane.
- Ichabod Crane
- Ichabod's Denial
The peculiar part of Ichabod's Denial is the subtitle of the Legend of Sleepy Hollow. This page of the Book of Fables goes through the legend of the Headless Horseman, revealing that it was a prank by a love rival to scare Crane out of the town. However as shown in the previous examples, the story normally correlates to a change in the character's personality. My hypothesis here is that the traumatic experience of the "prank" set itself deep in the mind of Crane, slowly simmering inside his head until the day when the stress exposes it.
Crane's outbursts towards others shows a lashing out of his feelings of worthlessness.
One of the more noticeable symptoms of clinical depression is the lashing out at others. This stems from the feelings of worthlessness that is a result of depression. The one suffering from the ailment will feel intense anger from the smallest of criticism as well as hold constant feelings of agitation and restlessness.
Crane is shown to be suffering from intense stress.
This is heavily shown through his demeanor, restlessness and the biggest piece of evidence; the antacid tablets sitting on his desk. While some people take the tablets regularly, it is often used to note stress in media. This stress can play a massive part in the emergence of his illness.
The Headless Horseman is the only character in the (in-game) Book of Fables that can be viewed but not selected.
Toad Jr's comment on how someone said to, "stop laughing". When asked further, he states that he heard only one voice and no laughing.
These last few pieces of evidence were shoved in our faces at the end of episode two.
- Crane is shown to have an obsession with Snow White through the photos.
- Crane is the other person that most often resides in the office regularly, giving him ample time to pinpoint Snow's perfume.
- Few would have the alibi to visit her in her apartment/office to get the picture of her let alone get close enough to steal a snip of her hair.
With these last pieces of evidence, I believe they are throwing us a red herring to suspect Crane. Later on I feel we'll find out that Crane himself is merely just a creep, thus throwing us off his trail. Near the end as the story develops I feel we'll learn bits and pieces more about Crane and his problems.
To sum everything up, I believe the killer is not Ichabod Crane but the Headless Horseman; a separate personality formed from a severe case of Dissociative Identity Disorder. I'm not thinking that Crane becomes "headless" when the Horseman personality takes over. I do however think "Headless" refers more to the personality's behavior; a homicidal maniac that decapitates his victims. I believe Crane is aware of this other personality and tries to control it. There could be several cases of Crane developing selective memory and not recalling certain events. TJ's comment points to a strong link with the Headless Horseman who we all know laughs maniacally and has a thing for decapitating his victims. This is just my own opinion I came up with while playing through the two episodes, let me know what you all think.
TL,DR: The prime suspect is the Headless Horseman; a split personality of Ichabod Crane.
Other Suspects: Dr. Jekyll / Mr. Hyde?
