Jason "Jase" Wirey was a HouseGuest in Big Brother 5 and later returned for Big Brother All Stars. In Big Brother 5, Jase became the leader of the Four Horsemen alliance and quickly took the fall once the alliance imploded. Jase became a huge competition threat, winning 1 HoH and 2 PoV's during his stay in the house. He was the fifth evicted, placing tenth and becoming the first victim of the now famous backdoor strategy.
Jase returned for Big Brother All Stars, after being selected by the public vote to enter the house. After winning the first HOH competition, he began to play both sides of the house, flip-flopping back on Chilltown and the Sovereign Six alliance. However, this came back to haunt him as he was nominated by James during Week 3 as a replacement nominee, which caused him to start trashing the backyard. He was evicted and placed twelfth. He was accused of being part of the Mr and Mrs Smith alliance with Diane. However, on finale night, this was confirmed as an alliance made before entering the house.
Jase was later a canidate for Big Brother Canada 4 but lost a public vote to Tim Dormer.
