S4·E11 Timeless

World famous pianist Claudia Jarsine has a secret that even she doesn't know -- she's destined to become Immortal. Immortal impresario Walter Graham, who has guided the careers of mortal greats like Shakespeare, sees his chance to shepherd Claudia's genius forever and kills her, triggering her latent Immortality -- against MacLeod's better judgment. Meanwhile, Methos has fallen for Alexa, a waitress at Joe's who has a secret of her own.
