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.
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.
Made even sadder with Derrick's grandfather passing away the day after.
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 int he 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.
