Alone

Outline:

Emily and Lena start putting on their space suits. Emily is done relatively quickly while Lena makes slow progress as she struggles to keep her balance. Half-way through, she gives up, sitting down on the bench next to the airlock. Emily helps her all the way into the suit. Lena sits there for a moment, heavily breathing, while Emily waits.
Sorry, I can't... I feel exhausted.

Emily takes their helmets and brings them into the airlock. She returns for a life support unit, pulls it out of the rack in the wall, and sets it down on the floor. Following a mental checklist, she makes sure that the oxygen bottle is connected properly and the gauges read what they should. Everything okay... or is it? She double-checks with the check list on the wall. Yes, this unit is ready. She triple-checks everything – first time it actually matters. Reasonably satisfied with her findings, she carries it over to the airlock. Then, she repeats this procedure for the second unit. Finally, she helps Lena up and they get into the airlock.

The pumps are getting quieter and quieter. Lena kneels on the floor holding a bunch of flowers from the biotope module, her life support unit next to her on a short tether. Emily puts it on her back and and helps her up. The outer door of the airlock silently swings aside and they start walking, Lena leaning on Emily.

They reach the graveyard and walk over to the recent graves. The entire graveyard is covered in hills where the bodies of the deceased were buried. Some have signs with names, some have painted pieces of regalith as gravestones, some have <the crumpled remains of>? What happens to flowers when exposed to vacuum for a prolonged amount of time? flowers next to them, a few are entirely undecorated.

Lena places a couple flowers on each of the most recent graves, then she gestures for Emily to take the life support unit off her back. Emily takes it off and she sits down. Emily places the life support unit behind her, Lena leans against it. She turns her radio on and Emily does the same.
Ultimately, you were right. She is interrupted by coughing. If more had taken Tony's cure – no matter what risk it posed ... – maybe some of them would be alive now.
What about you? Emily asks with a slither of hope in her voice.
No – no cure can save me, it's too late.
Emily tears up. note: Slightly. Is there a better way to say this?
I'm sorry.
Lena raises her arm. Emily sits down next to her and Lena puts it around her shoulders.
What will I do without you?
You have a strong mind. You got this. Jack will call in the evening, as usual; he will know what to do next.

missing:

The conversation is interrupted by the beeping of Lena's low oxygen alarm going off. Emily gets up and walks back to the habitat. She enters through the airlock and looks for a full oxygen bottle. She lifts one out of its rack and carries it back to Lena. She opens the life support unit and closes the valves on it and the empty bottle, then she replaces it and opens the valves again. Just as she is done with that, her own alarm goes off. Disappointed/annoyed reaction

Emily sits down next to Lena again, but there is no conversation.

Emily looks at Lena – she had closed her eyes. As if she knew Emily was looking she opens them, looking directly at her. Gripping? her hand as she speaks. some meaningful last words? Then she lets go and closes her eyes again. A couple minutes later, she stops breathing. wording

Emily sits next to Lena for a while, completely out of it, her mind being numb.

Her oxygen alarm goes off. Absentmindedly, she gets up and returns to the habitat. She opens the airlock, enters, closes the outside, and enters the inside. As she is putting away her suit, she realizes that she had been following the procedures from muscle memory without even thinking about them. She walks to the ??? module and lays down on the floor staring into the sky. This module has to be described at some point before this. It has panorama windows to all sides and a glass ceiling.
