2. Ethan talks to Ryker and Katie about the accident
I don't think that's a realistic expectation, although this obviously isn't a story that relies on realism. Ryker jumped the MC with a gang, injured him and his teammates, swung a bat at Harper and Willabelle, decked Wendy, and attempted to kidnap the MC more than once. He also has been running a smear campaign and trying to portray the MC as the instigator when Ryker is the one guilty of a lot of criminal activity including potential attempted murder (you don't swing a bat at someone's head and assume that person will survive).
Most people wouldn't want to speak to someone who'd done that to them and their friends.
3. (Optional) Ethan forgives Ryker and drops the charges since he does owe them a debt for his father's actions. Make it clear though it is a one time thing. Anything following will not be overlooked.
The MC doesn't owe them anything. He was a child when that all went down and had zero input. He didn't even know what the car ride was about (he was sick and getting worse due to neglect, so the adults who were trying to help had to get him medical attention against his father's wishes). He would've been their adopted brother if that crash hadn't happened, because Riley's whole intent was to get him away from his father.
MC: Did nothing, lost his father (and sister and mother until WVM), was in a coma from the wreck.
Ryker: Lost his parents, committed felonies to get back at the MC (and other people) for something the MC had no control over and didn't even know happened.
6. A conversation with Azel, Wendy, Rachel and Willabelle about Daliah.
The way this is presented, it seems like they'd have to maintain a publicly adversarial relationship, since Daliah's major influence relies on those in her business thinking she's on their side against Rachael, Willabelle, et al. Her subordinates are loyal to her, but the others in the larger criminal empire are not. Maintaining that opposition status would also agree with what Willabelle said beforehand. She thinks that she could possibly smooth things over with Daliah on a personal level, but not a professional one. Rachael's the biggest reason Daliah gained power in her company. The company knows she betrayed Rachael for them, but they also know that she worked
with Rachael for years
against them. So even with her current status as the owner of one club in the organization, any evidence that she and Rachael are working together would destroy her clout within the organization.
Daliah can probably be seen with the MC and his family (his family is uninvolved with his grandmother's industry and she's already aware that Daliah was on Azel's side for the adoption issue, so that would be an expected connection), but probably can't be seen hanging out with Willabelle and Rachael (business and ideological rivals/enemies of the MC's grandmother).
Curious to see how that is handled next year. "So it'd be kinda cool if you'd all be friends again, but you totes gotta act like you hate each other in public, k?"
