Prerequisite: After visiting Aya and getting Jaal onboard.
Talk to Suvi after getting Jaal and she’ll tell you that she’s detecting extra mass aboard the ship. You should use your scanner to find out what or who is onboard. Head to the cargo bay and inside Vetra’s room. Scan the rig welded into the ship’s structure.
Go back to the bridge and talk to Kallo to learn about the rig and play an audio recording from it. You’ll have the option to later keep in The Tempest or surrender it to the Nexus as part of history. Mission complete.
