From Thief: It's evident from the surface action in the film that Leo, Frank's 'boss' (left) provides Frank (right) and his partner, Jessie, with a baby boy, but as discussed in the separate analysis of Thief on this blog, a component of the 'hidden' plot is that Leo has also provided Frank with Jessie herself; or more correctly, he has provided Jessie with Frank, so that she and the child will have a means of support.
From Heat: Neil, Chris's 'boss', confronts Charlene about her cheating on her husband (Chris). Neil demands that she give Chris one more chance to make a big score and then not blow the money by gambling it away. (Chris lost most of his 'earnings' from the previous robbery due to debts from a visit to Las Vegas.) This conversation 'points to' the hidden plot in Thief, in that there must have been one or more 'behind-the-scenes' conversations between Leo and Jessie; these two characters are never shown in one another's presence, nor are they heard speaking with each other (such as over the phone), at any point during the movie (Thief). Thus, their conversations constitute action in the film that is 'hidden' from Thief's audience. This audience must deduce the fact that these conversations took place, based on the surface action in the film.
