I don't really think Alec is a bad teacher. I don't think he's never had a decent chance on this show, except with Toni and now Natalie. I'm glad to hear that there wasn't too much tension like it looked. I guess since Maks is gone they don't have any footage of him making his partners cry so they do the next best thing

I didn't think much of their rehearsal,
other than Alec getting frustrated and Natalie being frustrated and him basically telling her they could do it two ways but she needed to pick which way was comfortable for her. Since the dances were identical, and Natalie got such good scores for her rumba, she might have felt the pressure to top that.
They have the paso doble this week, so Natalie can bring out her swimming face, or whatever the heck she called that. I think this might be a good dance for them, if she can bring out the emotion needed. She's doing well with the footwork so that might be the easy part for her. And though they aren't scored according to other people doing the same dance, I think the paso group overall is weaker than the AT people, so she might have a chance to shine there.
