When the cook calls to you from the cafeteria when you first walk into crew quarter, it will give you a new optional objective. We’re going to include it here because you can walk away from the objective with another sample of Danielle’s voice.
Investigate the cafeteria
Carefully and quietly make your way to the cafeteria (unless you don’t care about people’s heads exploding around you). There’s a typhon telepath in here surrounded by mind-controlled humans.
Secure the cafeteria
Knock out the humans with your disruptor stun gun, nullwave transmitters or the mindjack ability, then you can turn your attention to the telepath. Nullwave transmitters and psychoshock will put it off balance for a few seconds, or you can knock it down with the GLOO cannon. After that, you can just pummel it with your weapon of choice.
Talk to the survivor in the kitchen
Meet Will Mitchell at the window. He’ll give you the Will Mitchell’s cabin keycard and ask you to retrieve something for him from his cabin. There’s something off about this guy.
Search the cook’s room for his award
Take the keycard and head over to crew cabins A. Will’s cabin is at the end of the hall on the right. Before you pick up the reward from his bedside table, check the TranScribe on his desk — this will get you a sample of Danielle’s voice, but also let you know what was so off about the cook.
Give the cook the award
How you proceed is up to you, but playing along is the quickest way to wrap this up. (Though, the cook is clearly an imposter and you’re well within your rights to knock him out or kill him.) Slide the award through the window, and he’ll unlock the kitchen door.
Head around and behind the counter to your right to find the door.
Replace the broken regulator
You have two options here: Fix the one on the floor with repair, or go retrieve a working one from the greenhouse up in the arboretum. It’s much, much quicker to just repair the one here.
The regulator in the greenhouse (which you can only get to without a fight if you’ve already completed "Savi Rani") is on the far side of the greenhouse from the main door, on the right side.
Search the freezer for supplies
Once you repair and/or replace the regulator, the cook will unlock the freezer for you to look for supplies.
It doesn’t go well.
Escape the freezer
When you are again able, head down to the end of the freezer and through the door on your left. Heartbreakingly, this is where you’ll find Abby’s body. Loot her corpse for a TranScribe with one more voice sample on it. This will get you the "Danielle Sho" optional objective.
Now you have to get out. Shoot the block of ice to the left of Abby with a q-beam blast (or pick it up with leverage) to get to the access panel behind it. This will lead you back to the kitchen, but the imposter cook (the impasta?) has fled.
Just be careful on the way out, since he’s booby trapped the door.
Restore from backup
The "Gathering Echoes" objective will end once you’ve gathered enough samples of Danielle’s voice. This will start "Restore from Backup," where you’ll use those samples to access deep storage.
