The father threatens that he’ll do everything that was done to the little girls, when the other man points out that also means raping him - they both act disgusted, not because it’s rape but because that would be gay… they discount raping him as a result.
The police reports indicate the little girls were drugged during captivity. Gidi bakes a cake to recreate this aspect and his father eats it not realising it’s drugged - he passes out soon after.
