'Big Brother 13' Spoilers Could Surprise Fans This Week

Big Brother 13 spoilers could really catch fans of the CBS show off guard this week. Those Big Brother 13 spoilers aren't simply limited to who was nominated for eviction though, but the revelation that Pandora's Box is making a huge return to the show this season.

According to Big Brother Network, which is one of the main fan sites for the show, Friday evening (Aug. 26), revealed another huge twist to the season. The current Head of Household was given the option to turn down Pandora's Box, or open it and win $5,000 for doing so. In the past, there have been both positive and negative events that happened from opening this box of surprises. This one might fall under both categories depending on which of the final houseguests a particular fan likes the best.

First it's important to take a step back, and reveal that it was Porsche who won the H.O.H. competition that took place late on Thursday night (Aug. 25). She was able to persevere against fellow houseguests Rachel, Jordan, Shelly, and Adam in the second competition of the night. It was at that point that Porsche was presented with the newest version of Pandora's Box.

The rules of the twist read as follows this year. "All the original duo rules apply. Duos will be nominated as a pair. If the Veto is used, they'll be removed from the block as a pair. If the duo remains on the block, they'll be forced to campaign against one another in order to stay in the house."

The week 8 nominations (by Porsche) were Rachel and Jordan, meaning they would need to win the Veto to save themselves. They comprised one team in the Veto competition, with the other teams being Adam & Shelly and then Porsche & Kalia. By choosing Kalia to be her partner, Porsche protected her from being nominated and also earned Kalia $5,000 for the save. Those were the teams heading into the Veto competition, which turned out to be an endurance challenge.

The Power of Veto results were the saving grace for Rachel and Jordan, as it turned out that Rachel had been the one to win it all. Now that duo will come off the block and it means that Adam and Shelly will be nominated for eviction. All of these Big Brother 13 spoilers will play out over the next week of episodes, with the nominations shown Sunday (Aug. 28), the Veto on Wednesday (Aug. 31), and then the week 8 evictions on Thursday (Sep. 1).
