Thought of how they could meet. Pre-time skip, Geist is on a mission to track down supposed survivors of Alsakan. It could lead them to Manaan, where they investigate suspicious activity at the H-something Station near the Star Forge. Slypher is assigned to the mission and accompanies Geist, hence why they're together.
