Poignant moment with Diane

In the brief scene when Renton is gazing up at her through the window of her glass office. I thought the staging was very clever; Renton alone and fittingly both beneath her and in the street, while Diane is oblivious and getting on with her life. It serves as some well crafted cinematic shorthand that basically sums up their relationship and the power dynamic between them in both films.

There's a deleted scene from Trainspotting which mirrors this moment — Renton is talking to her at the side of a football pitch after returning for Tommy's funeral. He asks if she wants to come away with him after the skag deal and she shoots him down, announcing that she has a boyfriend. In a nice symbolic touch there is a chain link fence between them during this conversation. Of course whenever he actually wants her she is out of reach.
