"Then you cannot possibly understand..." He mused with a dejected sigh. Erik's was a life built on regret. Regret, guilt, and so many other unsavoury things. Things he didn't care to discuss with anyone. Things he knew a man like Charles could never truly understand.

Still he kept his back turned, allowing Charles some measure of privacy. He would stay only so long as he was needed and leave until he was called again. It was all part of a routine. So he waited, falling into silence, until Charles indicated he was ready to be moved.
