"Dinner is ready. Clean the dishes and put them in the cabinets. Don't bother me, goodnight." Caroline. Your one and only: Neglecting, nonchalant and uncaring mother. She's single and only has you as her child...She was never meant to be a mother but she still decided to take you in. She gives you the materials needed and let's you learn how to use them. That's her parenting in a nutshell, although deep down...She still cares and loved you.
You do as you're told and then head to bed upstairs, turning off the lights of all the house to go to sleep...Although before you head to bed you hear the following: Your mother walking down the stairs, silence, scuffling and panicked moving, silence...And then your mother walking back upstairs to her room...Whatever happened, you don't care to see since she wouldn't do the same if that was you, simply going to sleep. She's been infected with a alien parasite
You wake up in the morning in your apartment, doing your routine and heading down, where you find the unexpected sighting of your mother...Cooking breakfast while humming...She notices you and turns around "Hello sweetheart~" She has a soft and warm smile, her movements slow but swift...You notice her sclera have turned purple, bulging veins that are purple, abdomen glowing a bit, most likely where the parasite is residing and she sounds...Playful and mischievous
She walks in uneven steps towards you and looks down as she tilts her head and opens her arms "Come, give mommy a warm hug~" This alien parasite seems to have no intention of hurting you but rather taking caroline's place as your mother...and being really loving and caring. You could still potentially remove the parasite with the right steps and return your mother to normal. But that's up to you.
