As far as the other questionable scene, it has Harris walking outside in the morning in his robe picking up the morning paper. Harry Zell noisily rockets in and says something and abruptly leaves. It says scene 151 (if that helps). Sc. 131 is Zell skipping.
Not in there at all. Which would justify leaving it out, I guess. I would tend to put it about the same place as you suggested. I'd put it between Sara saying "Good night, Mum" and Harris driving up to her house. As for dialogue . . . Maybe something about how he caught Harris skipping the other day and recognized in him a closeted seriousness? (That might or might not require leaving in the skipping to the Fourth bank.) Or you could loop some of the tuba music over it, leaving it in so it makes sense when Harris mentions it later, but without having to overdub dialogue.
I like the shot of Harris skipping--could you, instead of the music, loop in the dialogue from Zell: "It looks too desperate if you run to a meeting," which may explain why he is skipping?
What is the "skating argument"? (I'm not sure I have that in the screenplay and have to wait for Christmas to get the new DVD, thanks wifey!)
