1. MC abandoned her and had everybody, including her mother, keep his return from her. She don't owe him shit in terms of information. As far as we know, Ethan treated her well until he didn't and then they had a blackmail situation. i.e. she got in over her head.
2. Excusing Lexi's lie while calling out Erryn for not telling MC she was still involved with Ethan and the extent of that involvement is crazy,
3. Who said that she saw MC as that thirteen-year-old boy? The point of that question game that they've been playing is to learn more about the current him.
4. In what way is it immature of Erynn to act flirty with MC? If he doesn't like it he can easily tell her to stop it.
Im not sure how the onus for her interactions with the MC are all on her when the MC shut her out of his life from the time he left till the time she saw him in the bar.
Yes she was naive to get in way over her head, but does that have to do with maturity issues? no, it is life experience and her dealing with an obsessed ex- friend.
1: If she doesn't owe him anything, then by the same token of logic, he also doesn't owe her anything either.
If he's her friend, the friend she wants him to be, doesn't knowing how he hates Ethan and for good reason, she actually need to tell him sooner rather than later?
2: Again, not excusing her lie. I choose to forgive it. As the player, you are not given the choice to learn about Ethan and Erynn still being involved (whatever kind of relationship) together. You run into it at her apartment first (when he seems off put to be sure its Ethan, but I think he knows and chooses to ignore it) and then again outside the diner. Now, my MC doesn't care for Erynn that way, but the way it plays out MC definitely has strong feelings for Erynn whether or not romantic, that's debatable, but he feels a sense of betrayal from Erynn where Ethan is involved. Mind you, this is before learning the truth about what happened the day of his proclamation of love for Erynn. Its a justified feeling of betrayal in the moment.
Lexis lie is towards the MC, but her betrayal is toward Erynn. That's her bridge to burn and mend. Not MC's.
Erynns lie is directly towards the MC given how he feels where Ethan is involved.
There's a clear distinction there. Minute? Maybe, but it is there.
3: Her actions show that, with all of her proclamations in bed when he is sleeping and she states:
"You are the only boy who can sleep in my bed."
"I still owe you an answer."
Both of these statements are clearly talk about the past (5 years prior) as if it was a couple days ago.
And since you brought up the question game, she purposely avoids certain questions about her current status. MC does the same, so in this vain, both act immature.
4. Its immature of her to act flirty if shes not willing to see it through. This is actually one of my real gripes. I hear a lot about how she loves him as a friend and is afraid to lose the friendship by trying more.
The mature response is to make a choice and act.
Choose the friendship and keep it sacred.
Choose for something more and see it through and ACCEPT whatever consequences that brings.
She keeps staying somewhere in between and that is not ok.
MC is no saint. He's a short tempered baby who runs away and doesn't listen. Where Ethan is concerned though, I have MC's back like Nate.
Erynns naivety may have started the situation with Ethan. Her immaturity is what keeps her stuck in it instead of making tough choices before the MC arrives.
Life experience is when you make those tough choices and live with the consequences. She only chooses to do that once the MC is around. She's maturing because of the MC but she is not mature without him.
