In Westworld Season 3 Episode 8, the season finale, Caleb made his way through the riots to Incite, while Bernard visited someone important to his past.
In the previous episode of HBO’s Westworld, Dolores activated an EMP that shut down Solomon, Maeve, and herself.
When Serac had hooked her up to Rehoboam, Dolores had managed to lock Serac out of Rehoboam and give Caleb the only access.
Caleb made his way to a terminal to plug in Solomon’s strategy, but Maeve got to him and brought him to Serac.
