As unpleasant as it was to speak to Sev Larkinson, the session already bore a lot of fruit.
The Larkinsons and their partners gathered plenty of information about Ves' alternate personality.
So far, they have already managed to form a number of preliminary conclusions.
The first and most obvious conclusion was that Sev most definitely existed as a full and separate personality.
He was not a drunken or impaired version of Ves.
Sev existed as his own person. He possessed radically different views on a large variety of topics. The real Ves would never harbor those thoughts, let alone voice them with so much confidence and belief.
Second, Sev was rational and capable of communicating normally.
