Prerequisite: Establish outpost in Eos, at least on main mission “A Trail of Hope”
Head to the Hydrophonics area of the Docking Bay to find some protesters. If they’re not there, try leaving the Nexus and returning again. They’ll demand for their relatives to be thawed out of cryo-statis and they’re pointing the fingers at you for your decisions related to the AVP.
In any case, after talking to the protesters, you can head to Operations and talk to Kandros. Mention the protesters and he’ll call the other leaders. If you want to help the protesters, answer with “No, the protesters were right” and Addision will tell you about the cryo-stasis override.
Head to Addison’s office and interact with the main console to authorize the override. Rhys, the protesters’ leader will arrive and appreciate your actions. This quest will be completed afterward. You’ll receive EXP and AVP as well.
