Who does Holden think about after his fizzled date?

After his fizzled date with Sally, Holden stared thinking about Jane.

I thought maybe I might give old Jane another buzz and see if she was home yet. I mean I had the whole evening free, and I thought I'd give her a buzz and, if she was home yet, take her dancing or something somewhere. I never danced with her or anything the whole time I knew her. I saw her dancing once, though. She looked like a very good dancer.
