He uncovers the horrifying history of the castle: it was once owned by a Baron who tried to create an elixir for immortality.

However, Lockhart discovers that the Baron didn't die—he became the wellness center's founder.
The "cure" for trauma is not to kill it, but to integrate it. Lockhart has confronted the Baron (his own repressed monstrousness) and accepted that the darkness is part of him.

The opening scenes on Wall Street are key. Lockhart's boss literally drinks a green juice (a "wellness" product) while firing employees.

He drains his patients slowly, keeping them alive just enough to be useful. The sanitarium is just a corporation with a better spa.
