Ava will probably get along with her fine, just because she's not likely to set off any of her social justice stuff. That and even if she did, she would just smile and nod and think she is brilliantly fierce. But I actually think they would get along.
Albus will be terrified of her and yet incredibly interested. He will probably say stupid things and set her off, because that's how he is.
Eirik adores her already. He isn't going to fight with her, but he's also not the type to get into that situation in the first place. He's definitely willing to debate some things, as long as she doesn't start yelling. Then he will just smile and bow out of the conversation. Overall though, he is probably used to her by now and thinks very highly of her.
