In the fifth episode of The Crystal Cuckoo, we find ourselves in 1979, as a young Rafa embarks on a quest in the woods to locate his beloved dog. His mother, Raquel, has issued a stern warning to stay away from Gabriel, but the latter's charismatic presence proves irresistible. Gabriel not only aids in Rafa's search but also becomes his mentor, teaching him the art of being a "man" through hunting expeditions, the intricate Wing Beat Dance, and even introducing him to BDSM pornography. Raquel's discovery of this newfound friendship sets off a storm of fury, but Rafa remains unwavering in his loyalty to Gabriel.

As Magda's intimate relationship with Gabriel unravels, Rafa's presence at an unexpected moment leads to a tragic altercation that claims Magda's life in a fit of rage. Rafa flees the scene, burdened with guilt but unable to bring himself to confess the truth. Gabriel's departure from the town leaves a void that is soon filled by Rafa's marital infidelity with Silvia. However, a violent encounter with Rafa culminates in Silvia's murder, and in a panic-stricken state, Rafa seeks refuge in Gabriel's assistance.
Nine years pass, and Gabriel's return to the town is met with Rafa's fury and a desire for justice. Gabriel employs emotional blackmail, revealing his paternity and the threat of Miguel's disapproval if Rafa exposes Magda's murder. In 2005, Rafa grapples with his guilt, lashing out in drunken rages and questioning his own humanity. His encounter with Silvia escalates into a tragic climax, leading him to seek Gabriel's help once more.
Gabriel's presence in France after Luisa's murder becomes a source of solace for Rafa as he tries to navigate his own guilt and fear of being caught. The day after Silvia's disappearance, Rafa's frantic calls to Gabriel go unanswered until he stumbles upon Miguel holding Gabriel at gunpoint. In a moment of desperation, Rafa takes matters into his own hands, killing Miguel and blaming it on Gabriel's manipulation. Gabriel covers for him but offers more than comfort; he suggests teaching Rafa the "art of hunting," only to be rejected by the now-cautious Rafa.
Fast forward to 2023, and Gabriel's diagnosis with dementia paints a bleak picture of his future. Rafa has him locked away in the cabin, unaware that Gabriel has other plans. The kidnapping of baby Manuela was but a prelude to his true intention: donning the bird mask and assuming a life of secrecy and deception. As Rafa leaves the cabin, Gabriel prepares to embody his darkest self once again.
