Double evictions can shake up the Big Brother house and this season is long overdue for a power shift. All the pieces were in place Thursday: perpetual target Cody was definitely going to be the first evictee (and he went out like a boss) and Elena -- already on shaky ground -- swiping Alex's $5,000 Veto prize made her and her showmance Mark new targets, culminating in yet another kitchen shouting match with Josh. But a head-to-head knockout HOH comp basically ensured that someone from Paul's larger group (side note: Isn't it weird how there are no alliance names this year?) would beat Mark and Elena.
