[1] The regular episodes were intended as a celebration of the show's past and present, with five weddings featuring characters from different eras of the series, who were originally unable to marry for various reasons.

[3] All episodes were set over a four day period and were split between a wedding expo in Erinsborough and Elly Conway's (Jodi Anasta) 35th birthday celebrations on Pierce Greyson's (Tim Robards) island.

Finn lies to the other islanders by pretending Bea has returned to the mainland on the group's dinghy and is in Sydney by sending texts on her phone.

Elly celebrates her 35th birthday with her friends, though still remains worried about Bea and decides to leave the following day to search for her in Sydney.

After leaving emotional voicemails for Gary and Harlow, she opens her honeymoon package for a drink and is killed instantly by the bomb Finn planted.

After a chat with Paul, he accepts their relationship and Sky and Lana are married by Jack Callahan (Andrew James Morley).

After multiple events suggest the idea of marriage to Sheila Canning (Colette Mann) and Clive Gibbons (Geoff Paine), they are relieved to learn that neither of them wishes to marry.

When Mackenzie Hargreaves (Georgie Stone) and Richie Amblin (Lachlan Miller) arrive at the expo, they inadvertently slip while trying to explain where Hendrix and Harlow are and are forced to confess the truth.

After Toadie reveals what he knows about Finn, Paul is forced to flag down a passing vehicle to take him to hospital but they are horrified to discover that Harry is the driver.

"[7] Mills described the grave digging scenes as a product of Finn not being "a good or safe head space" because he has mentally "unravelled".

"[9] In the following day's episode, Elly finds Susan and Finn dies in a freak accident while preparing the grave, becoming the third death of the anniversary celebrations.

Meanwhile, when the surviving characters return to Erisnborough flashback scenes detail their escape from the burning island, while Harlow and Sheila are informed of Prue and Gary's deaths.

Subsequently, Elly is accused of causing Finn's death, with Mark and Sky both remaining in Erinsborough to investigate the crime.

[10] Elly is found guilty of involuntary manslaughter and imprisoned, but later released when it transpires that Finn's mother Claudia Watkins (Kate Raison) blackmailed her judge.

[12] Storylines over the coming weeks also explore the grief experienced by Harlow and Sheila, and the guilt of Susan and David Tanaka (Takaya Honda), who had neglected to recognise the danger Finn posed.

[17] Following the initial promotion of multiple upcoming deaths in January 2020, Daniel Kilkelly of Digital Spy speculated who could be the victims.

[24] Daniel Kilkelly called the drama a "game-changer", praising the fact that the deaths would have a long lasting impact on the show.

[25] Stephen Patterson described the week as being full of "love, laughter, tears, terror and all round unmissable drama" while noting that viewers could have many questions needing to be answered.

[28] Colette Mann and Chris Milligan, who play Sheila and Kyle Canning respectively, particularly praised Damien Richardson for his work on the show after his final scenes aired and wished him the best of luck for the future.

[29] Daniel Kilkelly of Digital Spy reflected upon the events of the Endgame episodes, noting that Finn's drama would have a long lasting impact on Ramsay Street's residents.

Kilkelly praised the immediate aftermath of the episodes managing to keep key characters on-screen, positively comparing this to EastEnders' own recent 35th anniversary period.

He also praised the initial explorations of the grief and guilt of multiple characters following Finn's actions, and the continued role of Mark and Sky in the coming episodes.
