Dissociative Identity Disorder (DID)

In the second scene of my production the main character tackles his own DID in order to discover more about himself and what has happened.

DID is a complex psychological condition which can be caused by server trauma. A person with DID is described by having two or more personalities/identities. These identities are often completely different from each other, with completely different traits, including: different age, race, speech, posture etc... But what I found most interesting about DID is that the identities often have distinct memory variation and different interpretations of the same memories. 

The main character fits this 'specification' for DID. As he has witness a server trauma; his own murder, both identities in this scene have completely different traits and personality. Furthermore the wholes scene is based on the two identities having completely different memory variation on how they died, one believing suicide and the other knowing it was murder. However, the one thing that is inaccurate is that they are existing at the same time and talking to one another. Then again this scene is taking place in the mind of the main character, which is also the place these identities reside.
