<Emily incoming call>

At some point before this chapter, the protagonists need to make phone calls happen – probably from the perspective of those on Earth as most of the things in the Lunar Biosphere have been at least kinda maintained.

Emily finds herself laying on the floor, still staring into the sky.

She lifts her head.

That's the phone in the control room.

Emily turns onto her side and slowly gets up. Her back hurts.

On my way, I'm on my way. she says in a soft matten? voice.

The phone rings a few more times but stops before she can make it there. She realizes how thirsty she is and takes a detour to the nearest kitchen. She thinks Water! Yes! but her excitement quickly turns into disgust as a brown liquid full of clumps sprudelt? from the tap.

After getting water from Tony's lab and feeding the mice – which she had also neglected to do – she goes into the main control room. The terminal for communication with Earth is lit up, showing a message. Emily sits down and writes in response:
Lena is dead.

She gets up and realizes that she had been completely neglecting her bodily needs (food, water, ...) and that her back hurts. She starts makeing her way to the main control center, part-way there the phone stops ringing. She goes to the nearest bathroom, goes to one of the kitchens to grab the next vegetable she can find, and heads to the control center to log on at a terminal.
