Oh ho ho ho! my friend, the mother's pin is NOT his gift neither is the card that he gives you.
No that's not it either...To get his gift, You'll need to:
1. Obey Cameron and refuse last second (ep 2)
2. Save the vhs tape (ep 4)
3. Be a good butler and wake him up early (ep 5)
4. Help Sultan treat his father's wounds (ep 6)
To get a gift you'll need to at least do three of these correct choices. Only then will Sultan gave you his farewell gift.
(Btw, this system is used for all chapters. So if you want to get all the farewell gifts keep that in mind!)
The performance menu could also be used as a reference whether the choice you've picked is good or not.
Additionally, the other choices would be Sultan's "interogations" about his mother's murder, the questions hinted this, however he's very subtle with it.
Whatever you chose during these three questions will determine whether Sultan deemed Rayne as Guilty or Innocent 🤫
