Ep 6 released Nov 13th, so we're not close to 5 months yet.
I did lay this out in my earlier theory, but I'll do it again in greater detail and with bullet points:
- Bella and Jill are playing tennis
- Tybalt interrupts them, suggests playing Jill
- Bella says no because it's just supposed to be her and Jill playing
- Tybalt suggests doubles and getting a 4th to join, goes to call a Prep buddy
- Bella says she has someone else in mind, Tybalt capitulates because he's trying to befriend Bella
- Bella, unbeknownst to Jill and Tybalt, calls the MC
- The MC shows up, Jill is surprised, Tybalt is pissed
- Bella gets annoyed at Tybalt, says she'll just leave if he won't let the MC join, Jill gets upset that Bella wants to leave
- Tybalt, in order to keep Jill happy, lets the MC stay so that Bella will stay, which is what Jill wants.
In this scenario, it's
Bella wanting the MC to stay because he's
her guest, and Tybalt knows how much Bella means to Jill and how much he needs to keep Bella on-side, so if Jill is upset at
Bella leaving, he'll capitulate because it satisfies two of his goals, being on good terms with Bella and keeping Jill happy, even if it means going against his own blackmail conditions.
