The Hospital Twist...
It seems fairly likely that in revealing Gino and Sabrina's father, Marcella also reveals the secret that he too is father to Pim.
Think about it:
- We never see Pim's father.
- Marcella reveals to Sabrina that Yvette (Pim's mother) slept with her husband.
- It explains the unusual bond that Marcella has with Pim, despite the fact that his mother helped destroy her family.
- It clarifies Sabrina and Gino's odd reaction to the photo. Sabrina's clasps her hand across her mouth at seeing the photo, hands it off to Gino, who immediately stares at Pim's face, looks back down at the picture, and hands it over to Pim. In the book Sabrina immediately notices that both Pim and Gino resemble the dad.
- The photo of the father actually does look like Pim, just with dark hair and a moustache.
- Earlier in the film Marcella thwarts Sabrina's attempt to have Pim over at the aunt's house. Could it be that she was afraid her family might note the resemblance between Pim and her wayward hubby?
- It sheds a completely different light on Marcella's last action of joining the boys hands together. A final deathbed confession and attempt to bring brothers together.
- It also fits in very well with the overarching theme of unusual/dysfunctional/twisted family dynamics rife throughout the picture.
