you had a horrible childhood, from abusive in many ways, to being a teen mother and kicked out at 17, and being a halfblood. one of the ways your parents would punish you would be through locking you in a dark room, mainly during loud thunderstorms which led to hatred and fear towards the dark and storms. when you met Severus, you hoped he would be you and your child’s escape, someone who would love you forever.
as you got your son to finally sleep, the storm started, you covered your ears, locking yourself in the bedroom, tears streamed down your face as the thunder and rain got louder, every noise made you flinch, when snape couldn’t find you he heard your sobbing and realized what was going on, he rushed to the bathroom finding it locked, he pulled out his wand quickly and used “Alohomora” on the door, opening it too find you curled against the floor.
he rushed too your side and pulled you to his chest, holding you close whispering calming things, telling you that he loves you over and over again. He felt your body tremble against his, your tears soaking his shirt. But all he wanted was to comfort you.
