So what would be your reaction if you were the MC and just found out? To go running to Erynn and tell her immediately (rather than fucking her Mom

) or to call and tell her, or send her a text and break the news to her that she's likely been thinking about most of her life?
Or to wait for her Mom to sit her down and let her tell her, like you've been asked to?
And I'm not sure what the news of John being Erynn's father has to do with what happened 5 years before. If anything the MC moving away led to him meeting John through Iris and then for Erynn to ultimately meet her father.
