As Midsummer festivities get underway, the Mercy Point cadets are sent to keep an eye on the partying crowds. Before they leave, Lekan secretly changes the round in Callum’s rifle to a live one. At the festival, the nought cadets are attacked as traitors by their own people. Jude is among the baying mob, shouting in disgust at his brother. Lekan orders Callum to raise his weapon.

Clearly conflicted, Callum points it at Jude (Josh Dylan) but Elaine (Jodie Tyack) – who saw Lekan tamper with the rifle – knocks it so that his shot hits the roof. Ashamed of his actions, Callum throws down his rifle and walks away from Mercy Point.

He soon runs into Sephy and the two head back to his house. Callum updates her on his decision to leave Mercy Point and breaks down in tears. Sephy comforts him, which quickly turns to kissing. And then, erm, removing each other’s clothes.

In bed afterwards, Callum questions what kind of person he is to point a gun at his brother. He also echoes Sephy’s earlier concern that things will never change for them, adding: “We’re just two people… but I want you, I really want you.”

Before any decisions can be made, though, the pair are interrupted by Meggie, who tells Sephy that her mum has been rushed to hospital. Which, naturally, proves to be a total mood-killer. Sephy rushes to be with her family at her mother’s bedside, leaving Callum alone.
