Kevin Wilson used to work with Triplet but was seduced by the 'dark side' of the Order and now works for Forrest.
For years he has run D'Netics and as such was Donna's immediate boss. What isn't apparent at the story beginning is that he was involved in the death of Donna's parents, something he feels deep regret over. You won't find out much about that story in 'A Vested Interest' but you'll find more of the story in the prequel series book 'Blood of the Rainbow 2- Roses and Regret'.
He is married to a much younger wife who is pregnant with 'their' first child. He is devoted to his wife and when she is threatened by Forrest he risks Forrest's wrath to get her to safety.
