You see the outside of her house, and you hear a little about what's happened around her, but you don't really realize how bad things are until you step inside Aubrey's house.
I've heard mixed opinions, but I personally think it's nice of Hero, Kel, or Sunny not to bring this up with Aubrey. That they didn't start a whole "Why didn't you tell us?" "We're friends, we could have helped!" "Why didn't you trust us?" kind of conversation. They had no idea what Aubrey's home was like, except for maybe Sunny depending on how you read into some things. It's clear that Aubrey was keeping everyone in the dark for a reason. She might be not be comfortable with the topic, or just doesn't want them to bother her about it. Or was ashamed. It might seem contradictive to say they're being good friends by ignoring the problem, but it's nice of them to not criticize or reprimand or get on her case for keeping this from them, or offer unwanted help now or later. And if Sunny does know about Aubrey's situation, I think the reason she would have told or showed him is specifically because she knew Sunny would just listen and not do any of those things. If she had wanted help back then, she'd have gone to Mari or Hero or their parents. Maybe. I think.
In the game Aubrey's Mom is completely silent, but in the manga she does talk to Aubrey briefly. I wonder if she'll say anything to Hero, Kel, or Sunny when they barge in. Or how the scene will be handled there since the manga's changed quite a few scenes already. I'm curious how it'll go.
