Emily pissed me off; she was willing to go along with Andres's demands until she fucked up as a mother. The reveal came from something that had nothing to do with him at all. She was willing to have Andres raise him as a child when he became too difficult to raise, but when it came time to own up for her fuck ups, she threw his ass under the bus.
As for the Erryn situation, yes, Erryn was a dumb child who underestimated her control over Ethan. Honestly, at that age, most children are stupid. As far as she knew, Ethan was apologetic for what he did to MC. MC was also a dumbass for running off without talking to her, but ya know, child. I'm not mad at anyone in that situation for what they did because it gives these people flaws, which I'm fine with.
