Casablanca

25: Rick is at the table talking with Strasser and Renault. The discussion is about Victor and there's disagreement about whether or not Rick is someone the Nazis should worry about. Ilsa and Victor enter Ricks for the first time. Ilsa and Sam exchange a look. The birth of something new.

45: Rick and Ilsa with Sam in Paris. They talk about leaving Paris on the train, Rick talks of marriage. Ilsa looks sad - she's aware that Victor has been found outside of Paris - she tells Rick she loves him very much, and they kiss as if for the last time. Only later in the movie (a few minutes after -25) will Rick learn that back in Paris Ilsa thought Victor was dead. Now that I'm aware.

60 and -45: Victor tells Ilsa he loves her very much. They search for two exit visas and learn from Ferrari that Rick has the letters of transit. Victor and Ilsa realize Rick is the one who decides whether or not they will escape from the Nazis. There's no going back now.

-25: Victor and Ilsa talk about the letters of transit and why Rick won't help them. Victor tells Ilsa again that he loves her. When Victor leaves to go to a meeting, Ilsa says be careful. We know she still cares about him. The next scene Rick learns that Ilsa still loves him after Ilsa implored Rick to "Put your feelings aside for something more important." Later, despite his feelings, Rick will give up the letters of transit to help a cause. The final turning point.
