Warning: Spoilers ahead for "Westworld."

HBO's sci-fi series has used multiple time frames and flashbacks over the last three seasons, often challenging fans at home to understand when a scene is happening.

So Insider created a chronological timeline of all major events from "Westworld."

To help "Westworld" fans better understand the events that have happened so far, Insider has put together a chronological timeline of every major scene in the HBO series.

The events are marked to indicate whether the scene was featured on season one, two, or three (either through expository dialogue or in a flashback/flash-forward) as well as which episode the revelation appeared on. This is not an official HBO-issued timeline, so note some events (or their placement) are subject to change based on new episodes.

Since some events are not specified within the show, we've approximated their location in the timeline. Those events are marked with an asterisk.

We've also split the timeline into two sections: Events from around 2021 up to 2058, and then everything from "current day" in season one to the latest events in season three.

This version of the timeline contains spoilers and events from season three, episode eight, "Crisis Theory."
