After the humans get their children back, Marcus attacks Mother violently after Paul runs off with her eyes (that weaponises her). She is kept as a captive for a while but she manages to escape. She has lost a lot of her liquid (Android blood) and goes back to the fallen Ark to fix herself. There she connects to older androids and transfers liquid into herself. She talks to a android doctor called Karl, and she asks him why she has a discomfort in her abdomen. Maybe she has to relieve some pressure? She cuts herself up but it does not help. Karl then suggest to look inside herself to see what`s in there. She takes out her eyeball, looks at her self for a second then inserts it inside of herself. She finds a growing thing in there and she does not understand what it could be. Karl suggests silicone tumor.
