Tear Jerker / Big Brother
In BBCan, Emmett telling Talla that she was going to be evicted. She was reduced to tears. When she walked out o the house, she stopped and spread her arms over the door, still fighting back tears.
Funnily enough, it was just like what happened in BB12 to Britney, although Britney took it better.
Before Talla, BBUK had Kathreya. Similar to Talla, she was one of the most carefree and friendliest houseguests ever, and at one point a choice to win. However, a surprise double eviction a few days before the finale started with the eviction of Mohamed (somewhat of a Shoot the Shaggy Dog story given his status as an Elimination Houdini) and then the next evicted houseguest was Kathreya. You could hear her and the rest of the houseguests crying because she had to leave.
Nick's untimely eviction in Big Brother 15. He was shown to be one of the very best plotters and schemers in the pre-show interviews and had one heck of a chance going in... if it wasn't for that dickhead Jeremy screwing over everybody in his vicinity, Nick included. Poor nick went out second, and the season quickly went to shit thereafter, run by complete assholes from nearly start to finish. Nick, please come back to the show someday!!
Judd's eviction in Big Brother 15. It was unanimous. Almost everyone was crying about it. Poor Judd...
It was even worse in the recap that Sunday, where it showed us that during the commercial break everyone burst into tears while Judd sat there pleading for his life in the game.
Say what you will about Amanda, the episode before her eviction was one of the biggest tear-jerkers on the show yet.
For starters, she was expecting Ginamarie to put Elissa and Spencer up on the block, so when she and her boyfriend McCrae were put up instead, it came as a total surprise.
She then angrily accused Ginamarie of betraying her, going as far as to say she didn't want to be in the house anymore.
During the veto competition, it came down to Amanda and McCrae of all people during the final round. Cut to McCrae beating Amanda by less than a second to win the Veto and keep himself safe. This was one of the few times they didn't play the happy winning music, instead leaving the scene silent as Amanda cries her eyes out, realizing she is going home on Thursday.
During the Veto ceremony, Amanda again bursts out in tears as McCrae uses the Veto on himself and sealing her fate in the game.
Finally, despite getting a Hope Spot when Elissa decided to save her (which means she would have the majority of the votes to be saved), Amanda's former ally Andy formed a new alliance, turned and evicted her. After that she had to face the boos by the audience due to her behavior in the house..
McCrae's Heroic B.S.O.D. after Judd's eviction makes it seem like he lost his significant other. And he didn't react that way when Amanda was evicted.
The fourth eviction of Big Brother 16 had several:
Frankie receiving news that his grandfather had passed away from cancer.
Brittany being greeted by her children after she was evicted.
Derrick throwing the HOH so that Frankie would get a picture of his grandfather.
It's hard not to feel for Britnee and Sarah in BBCan3 after Canada voted them Have Nots for the week. Sure, the reason they were voted in was because Canada wanted one of them to win a huge secret power, but they didn't find out about that part for a while - which means they spent several days thinking that their entire country hated them.
Also from that season, the entirety of Willow's eviction. Firstly it was the result of Sarah thinking that nobody would vote to save Willow, even though if she had voted for her then she would have kept her in the game. As soon as she realized what she'd done, Sarah burst in to tears. A few weeks later, when Willow was in the jury house and Bruno arrived, he told her that Sarah was the one who voted her out. Since nobody knew what Sarah had been thinking, they all thought that Sarah had stabbed her best friend in the house in the back just for the sake of it. Everybody felt sorry for her.
Jade Goody finding out she had cervical cancer during Bigg Boss 2, and dying just 6 months later.
Ensuing Black Comedy aside, Angie Bowie finding out about her ex husband's passing in CBBUK 17.
Pete from BBUK 7 had such a bad drug problem that he later admitted that he was on LSD during his interview, and only wanted to get on the show because he couldn't save up enough money for rehab. He only successfully became clean after spending all of his prize money and being homeless.
Vanessa finally collapsing into tears after turning against Austin. Not helped that Austin retorts, "You're not gonna get the jury votes."
Jason's completely accidental breaking of Christmas's foot on BB19 when he was letting her ride him on piggyback but tripped and fell, knocking her to the AstroTurf on it. Initially, it seemed like it would be a simple break that she'll be able to heal from... then she learns it is a Career-Ending Injury that is going to have real-life consequences, requiring surgery, a donor bone to replace one too broken to mend, and the very real possibility that she will not regain full mobility of her foot. Being an athlete, this is the darkest possible outcome. Jason inadvertently did one of the worst possible things ever to happen in the Big Brother house without meaning to- crippled somebody for life- and nearly broke down upon hearing the news. And yet she still chooses to stay in the game even when she knows she will need more surgeries in the future and already had to temporarily leave the house to go to the hospital, and will not be able to participate in some challenges if she isn't cleared to compete with her injury. Christmas is thus forced to sit out most of the competitions and spends half of her time on the show in the sidelines.
The second Double Eviction Week of 19 hits everyone like a ton of bricks, especially Josh, who is being forced into choosing his alliances over friendship. Jason and Raven are betrayed out of nowhere and Kevin stays in the house, leaving Alex in a state of despair, Jason dumbfounded and sore, Raven in hysterical sadness, Paul exhausted, Christmas on the verge of crying, and Josh... Josh is just blubbering by the end of the night. Jason is blindsided and has no words to say about the so-called "friendship" in the house and all the counterfeit people in the house who have been played by Paul just as he has now (an irony which is not lost on Jason when he tells Paul he can take his "FRIENDSHIP" bracelets and throw them). Worse, Paul's goodbye video to Jason is a thinly-veiled effort to gain his sympathy for the jury votes. Raven doesn't even get the benefit of the goodbye messages because there was no way to anticipate the need to record them for her in the span of such a short eviction, and runs out of the house rejecting the apologies from the rest of the house. Alex sits by the fridge, grabs the whole bottle of Coke, and looks ready to up and cry. Paul also admits he hated the entire night and was crying by the end of it. This night was so bad, the producers actually loosened up and allowed Alex to have alcoholic beverages on the show, just so Alex and the houseguests could drink away the pain...minus Kevin.
Megan Lowder. Oh, God, Megan Lowder! Her short time on BB 19 saw her Mistaken for Racist, ostracized, vomiting and diarrheic from nervousness, and finally collapsing into a panic attack in the Diary Room, causing her to walk from the game at the urging of the show's producers and be rushed to the hospital, where she spent several days drying out from the house's toxic atmosphere. Evidently, Megan was really traumatized, because after she walks from the house, she's virtually erased from the show, never featured in any evictee-themed competitions, and doesn't even come to the finale celebration. It's just plain SORROWFUL!!
Poor Paul, bridesmaid in BB 18, bridesmaid in BB 19 once more. Yes, he was a Manipulative Bastard, but to lose in the exact same waytwice (the only contestant in the history of the US version to suffer that fate) and coming to regret his menacing game, it really eats at him. Josh expected Paul to win, and even was proclaiming nervously, "You won, you won", when Cody's vote came up. When Josh one, Paul immediately hugged Josh, and seemed to be okay with the win, telling Josh to hurry on out and not keep the others waiting... but as Josh leaves the house as the victor... Paul stalls behind. You can see him quietly going over to the memory wall to presumably watch his image turn monochrome and accept his loss with grace, but really, Paul's in a salty mood unlike any other and stewing behind closed doors. when he finally lumbers out of the house, while everyone else is full of glee, Paul sounds absolutely wrecked and has a full "fuck me" vibe going on. The one good thing is that he's managed to attain one fifth of the grand prize now and is able to recognize that yes, he played himself all over again.
Big Brother Denmark subjecting the houseguests to the absolutely CRUEL treatment of having them forced to stay frozen in place as their loved ones come see them... it's no wonder the houseguests broke out and rebelled by the end!!!
