The small number of lines imply it's small variations that are missing. Off the top of my head it could be :
- Meeting the green-haired kid (Lee) in Zane's route.
- Meeting the white-haired kid (Kai) in Daire's route.
- Choosing not to spend time with your husband in each of the getaway combinations.
- A variation in the auction aftermath in Daire's path based on whether his affection is high/low
- An extra line or two in both versions of the play during Kiron's route if you have seen the dress rehearsal
