How to unlock: A message from Suvi [Nexus: Docking Area].
This section contains a walkthrough for Lexi T'Perro: Bottom of a Bottle - one of "Allies and Relationships" quests found in Mass Effect Andromeda. We are looking at an emergency - Lexi T'Perro, one of our crewmembers, has left the ship, nowhere to be seen. Our task will be find her and to the heart of the matter.
Unlocking the task
The quest should be unlocked automatically after you've managed to advance the main storyline and had strengthened your relationships with Lexi T'Perro thanks to frequent conversations on board the Tempest. During one of the visits on Nexus you'll receive a message from Suvi saying that Lexi had suddenly left the ship and that nobody can find her.
Search the Nexus
Fortunately, finding her isn't that hard - Lexi T'Perro is at the Vortex Bar in Nexus: Docking Area. Talk to her and choose the dialogue options that will improve her mood.
