The Lost Brother in Space — Episode 17

Timothy, adopted by the wealthy Snyder family, devotes himself to his three older sisters. Everything shifts when Matthew, the biological son, returns and uses manipulation to turn them against him. Cast out and framed for crimes he did not commit, Timothy remains loyal, sacrificing himself to join the secret Project Hail Mary, a mission to save humanity by sending a rare-gene carrier to colonize a new planet. Only after his departure do the Snyders discover Matthew's deceit and Timothy's sacrifice. Thirty years later, Timothy succeeds on Artemis as a hero, while his mourning family carries the burden of their betrayal.
