Adults
In the cloudy morning of Day 141, the Teen and Adult Big Four arrived at the Province of Albay after a 10-hour road trip. Upon arrival, they were greeted by Enchong Dee and Robi Domingo at the Cagsawa Ruins and announced that their Big Night will be held at the Albay Astrodome and at the adjacent Penaranda Park in Legazpi City, Albay's capital city.

Later in the evening, the Big Night live finale was opened by a spectacular performance from the past housemates and the Big Winners of the previous 11 seasons of Pinoy Big Brother. Together with all other housemates and Big Winners of the past 10 years including the 737 teen and adult housemates, Pinoy Big Brother: Teen Edition 4 Big Winner, Myrtle Sarrosa led the performance for the 10th Anniversary Song, "Salamat Pinoy (lit. Thank You Pinoy)" while the main presenter, Toni Gonzaga sang the Pinoy Big Brother theme song, Pinoy Ako.

The 7-day open voting was officially closed and the first set of announcements were made. Bailey May and Dawn Chang were named as 4th Teen and Adult Big Placers respectively while Franco Rodriguez and Roger Lucero were named as 3rd Teen and Adult Big Placers.

When the final two were about to anticipate the announcement of the Big Winner, Toni announced that the next set of announcements would be done the following night and for the first time in the history of PBB and in the Big Night, voting for the final 2 was reset to zero, to which the four remaining housemates reacted in shock. Before the episode ends, Toni gave the remaining housemates a chance voice out their pleas on why they deserved to win the title of Big Winner.

The second evening of the Big Night was opened by a dance performance from the 737's adult and teen housemates, as well as the recently announced 3rd and 4th Big Placers at the Penaranda Park. Meanwhile, inside the arena, the first ever Teen Big Winner, Kim Chiu had an opening dance performance.

During the second day of The Big Night, the season's charity mission of collecting P3,000,000 was achieved and the proceeds were given to Habitat for Humanity Philippines for the benefit of the construction of new houses in local communities of Bohol which were severely devastated by Typhoon Yolanda, spearheaded by Slater Young, PBB: Unlimited Big Winner.

After the 24-hour open voting, the second set of announcements were made. Ylona Garcia was declared as the 2nd Teen Big Placer, making Jimboy Martin the Teen Big Winner of this edition by a close number of votes. Despite the fact that they made their relationship throughout the entire season, Tommy Esguerra was declared the 2nd Big Placer while Miho Nishida was declared this edition's Big Winner by a huge margin.

All Big Placers were transported from the Albay Astrodome to the stage just a few meters away to Penaranda Park through ATV vehicles, while Miho and Jimboy did the same thing, but this time, as part of the tradition of Big Winners, made their grand exit through the prop- base platform of the Cagsawa Ruins riding together in their ATV vehicle with showers of confetti.

These two nights also marked the absence of Bianca Gonzales (due to her pregnancy) and the return of Mariel Rodriguez as host after five years, similar to that of Toni Gonzaga in the Big Night of the first Teen Edition and prior to her role as the last celebrity houseguest.
