There is an in game walkthrough, if you've gone down that route; then you got on the bus, and either fought the molesters or didn't - met Vivian, after Vivian and Dicky you either stuck around a bit or left at which point you had either the male or female police officer and then onto George.
You could have not gone into the bus stop.
You could have said no to Dicky sticking around and then there are three choices, fight, run or submit. All three choices result in something different.
Depending on those choices, will depend on various other branching paths. The in-game walkthrough is deigned to take you through the game and see all the content, additionally, there are the achievements too which will all pop up during and all show as complete once you have seen everything.
