Big Brother houseguest Megan Lowder evicted herself from the house, leaving Cody Nickson to name an immediate replacement nominee on the chopping block during Sunday night's broadcast on CBS.

Megan, a 28-year-old dog walker from Cathedral City, CA, who currently resides in Phoenix, AZ, quit the game after her fellow houseguests lost trust in her due to a controversy involving a racial slur.

Megan had been on the chopping block with Jillian Parker, a 24-year-old timeshare sales representative from Celebration, FL, who currently resides in Las Vegas, NV, but because of her self-eviction, Cody had to name a replacement nominee.

Cody, a 32-year-old construction sales representative from Lake Mills, IA, who currently resides in Plano, TX, therefore decided to nominate Alex Ow, a 28-year-old eco-friendly marketing representative from Thousand Oaks, CA, who currently resides in Camarillo, CA.

The Big Brother broadcast began with Paul Abrahamian calling the players in this game "stupid" because he expected to be nominated for eviction week after week since he's a returning player who came very close to winning Season 18.

Meanwhile, Megan was upset about the way Cody had nominated her for eviction.

Cody had announced to the house he simply didn't like Megan and that Jillian was the other nominee because associated herself with Megan. Megan didn't appreciate the personal attack, saying it was uncalled for and really hurt her feelings. Megan was already reeling from Josh Martinez's attack on her during the previous Head of Household competition.

The way the houseguests were treating Megan made her feel anxious, paranoid and stressed out.

Megan's social game plummeted once she informed her friend Alex that Jessica Graf had allegedly called her a "panda" behind her back. Alex didn't care that Jessica was talking about her behind her back, but she thought the term "panda" was incredibly insulting and disrespectful to her family.

Alex trusted Megan at the start of this game, but when she confronted Jessica about the racial slur, Jessica completely denied every saying something like that and insisted Megan was just trying to get the heat off of herself since she was on the chopping block. In that moment, Alex believed Jessica and couldn't believe that Megan had lied to her about something so serious.

Alex eventually confronted Megan about the situation, and Megan stood her ground, saying Jessica did in fact use the word "panda." But no one believed Megan and it was clear even her closest allies were done working with her.

Megan therefore locked herself in the Diary Room for several hours, crying to the cameras about how she didn't deserve this type of reaction from her fellow houseguests.

Cody then gathered the house and read the following from a card: "Due to an urgent personal matter, Megan will no longer be participating in Big Brother this summer."

It was a shock to the house that Megan would quit the game, because it seemed like everyone was still concerned for her well-being. Cody was then told he must name a replacement nominee the next day, so he seemingly had 24 hours to think about a gameplan.

Cody respected Alex as a player because of how long she had lasted in the first competition of the season, but everyone in Cody's alliance -- Jessica, Mark Jansen, Matt Clines, Elena Davies, Raven Walton, and Christmas Abbott -- wanted her gone. Raven even suggested to Cody that he should tell Alex she's a pawn this week so she would feel safe and potentially throw the Power of Veto competition.

Cody, however, tried to align with Alex in some way in order to save her, but Alex was stubborn and proud. She wanted to win this game on her own merit, not by riding someone's else coattails and listening to someone's demands. Cody realized that Alex wasn't having it.

Alex also alarmed Cody because she said she wanted to break up a power couple in the house if she became Head of Household next week. Cody, who was flirting with Jessica, just so happened to be one of those couples dubbed "Jody," along with Elena and Mark called "Marlena" and Matt and Raven called "Maven."

As a result, Cody ended up nominating Alex for eviction along with Jillian. Cody told Alex that he wanted to see her fight in the Power of Veto Competition because he had a lot of respect for her -- which is exactly why he didn't attempt to backdoor her.

Paul also received a couple of advantages in the game during last night's episode. He took a "Have Not" temptation which gave him a 50/50 chance of either dropping his "Have Not" title for the week or extended it by an additional week. The "Have Nots" this season must sleep on a bed of spikes, so it's arguably the most uncomfortable room ever on Big Brother.

Paul picked the correct box and got out of being a "Have Not."

America also selected Paul to receive a temptation in the "Den of Temptation." Paul was offered the "Pendant of Protection," which means he'd be protected from the next three evictions, meaning he could not be evicted from the house or even nominated for eviction. If Paul chose to take the advantage, however, it would mean another houseguest would be in jeopardy of eviction for the next three weeks.

Paul learned that if he chose to take the temptation, it would remain a secret unless someone attempted to nominate him for eviction.

Since it was such a huge advantage in the game, Paul accepted the temptation. He was then asked to randomly choose one numbered bottle of potion, with each bottle representing a particular houseguest. Paul chose a bottle without knowing which houseguest would be cursed thanks to his action in the den.

Paul told the house he received a "sorry" card.

Big Brother host Julie Chen later revealed to the house that the temptation had been accepted and therefore a consequence would be released into the house "in due time." No one knew Paul was behind the temptation. In fact, everyone thought it belonged to Josh because he was walking around the house smiling from ear to ear.

Home viewers are now voting for one Big Brother houseguest to receive the "Ring of Replacement" in the Den of Temptation.
