Being Erica:

Dr. Tom is the mysterious therapist who enters Erica's life when she is most vulnerable, desperate and in need of a change. He proposes to transform her life radically, offering her the astonishing opportunity to go back in time to alter her fate.

Dr. Tom's therapy sessions and methods are just as bizarre as the circumstances in which he met Erica, and at times infuriating. He reveals next-to-nothing about his techniques and rarely answers a direct question, preferring instead to toss around peculiar quotes and random asides. He maintains the wellkept secret of who he is, and how he knows so much about Erica's life, with near-flawless discipline.

As elusive as he seems, however, there is no doubt that Dr Tom understands the human condition and psyche better than most.
