Angel and Victor are the ideal coaches in my opinion. They're tough but they value and really love each of the dancers, and all of the kids, miraculously considering their mothers, seem to be sweet and work well together. The only kid who I don't think is very nice is Sammy. She was awfully quick to blame Kimmy for the mistake during the dance. Jessi seems to be trying really hard since getting called out, good for her, and good for Angel and Victor for dealing with that so well.
Kimmy is just adorable, and I really like her mom. I also kind of like Sammy's mom, I forget her name, but she seems to be almost normal. I like that she says to Susan that it's not okay to say in front of everyone that Jessie is the best dancer in the studio. At fourteen, yeah maybe she is, but I think it's clear that both Kimmy and Lucas are exceptionally talented.
Poor Hannah that she knows that none of the parents want their children to dance with her. It's a mark of the genuine goodness of the girls and of the coaching that that attitude doesn't seem to have transferred to the girls.
Lucas's mother is just evil. No two ways about it. To confront a child the way she did, even if Sammy was wrong for blaming Kimmy, was just completely out of line. And that's just one awful thing she's done.
I think there was probably more to the conversation between Lucas and Victor about him being bullied, and honestly I'm glad that the onscreen version was short and just let the viewers know it was happening. Victor really seems to care about Lucas and I'm sure if he was having trouble they had a real, honest conversation about it, but it's probably better for Lucas not to have to have such a difficult conversation on camera.
