why does theo leave home and away

Theo leaves "Home and Away" because his character, Theo Poulos, is killed off in a dramatic storyline. The character dies after being hit by a vehicle driven by Councillor Craig Wendell during a confrontation meant to protect his girlfriend Lacey Miller. This heroic act marks the end of Theo's journey on the show and makes his return highly unlikely. The actor Matt Evans, who portrayed Theo, left the series to pursue career opportunities in the United States, and his character's death symbolizes a significant and emotional exit after four years on the show.
