The following contains spoilers from the Big Brother live feeds as of Wednesday, July 29th. Kamu's Week 3 HOH reign in Big Brother Season 28 is almost at an end. Unfortunately, the plan to keep Jason and Mallory only works at this moment if Jason wins the BB Blockbuster. Suffice to say, it's going to be a big Wednesday and Thursday morning, as a few Houseguests need to decide whether they're ready to play Big Brother for themselves, or for the vets. Big Brother airs on CBS on Wednesdays, Thursdays, and Sundays at 8:00 p.m.
