Raised by Wolves (Insert eyeball to find anomaly inside body)

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.
