Oh, ok. Bear in mind I'm fairly new to programming, but my understanding is that generally when there's a more permanent change to game state (i.e. across multiple scenes and not just the next scene) the programmer will set a variable that defaults to False and cause the game to change it to True when an event triggers it. For example, you can create a boolean variable called "talked_to_Alex", with default value of False, and part of the code for when you click on the appropriate choice is "talked_to_Alex = True". Then later any code that needs to reference that event can use "if talked_to_Alex:".
