How the Slytherins would react and Slytherin imagines

Halloween party - Theodore

You and Pansy were currently in your dorm. You were getting ready for this years Halloween party. Pansy dressed up as an angel and dressed up in all black and did a skull make up. After you were ready, you headed to the common room.
When you arrived you immediately spotted your friends in one of the couches. You went to them and tried to find two empty seats. Well, Pansy didn't need one since she sat on his boyfriend, Blaise's lap. Luckily, you didn't have sit on anyone's lap because there was an empty seat next to your boy best friend, Theo. You plopped down next to him and looked at him. He was in all black just as you and just like you he had a skull make up. You smiled at that. You didn't talk about it, but your costumes are matching. You were not the only one who noticed that. Pansy noticed it too.
"Did you talk about matching costumes or something?" she asked, and you shook your head.
"No" Theo said and looked down at you. He leaned down to whisper in your ear "You look pretty"
"Thanks. You look good too, Theo" he smiled at your compliment and put his arm around your shoulders.
You were just sitting, drinking, and talking for a while. But when you had enough alcohol you and Pansy went to the dance floor. You danced together for the rhythm. You were swinging your hips and enjoying yourselves in the dance floor. You felt someone's eyes on you the whole time, so you looked to the side to see who's watching you. Your eyes met with Theo's. You mentioned for him to come and dance with you, but he just shook his head and only watched you.
After a little time, Pansy disappeared in the crowd, so you were dancing alone, until you felt hands on your hips and that someone's pressing against you back.
"Hello, pretty girl" a low voice said. His voice wasn't familiar, so you tried to push the guys hands away, but had a firm grip on your hips.
"Leave me alone" you said quietly and turned around.
"Come on. Come with me to my dorm. We can have fun" you felt the alcohol in his breath. He was clearly drunk. And you didn't like that.
"I don't want to go with you. Thank, I'm good" you tried to push him away from you, but his hands from you hip wandered to your wrist. He grabbed it roughly and started pulling you to the dorms.
"Don't act like that. I know you want it too, slut" he strengthens his grip on your wrist and continued pulling you after him. You start to panic.
"Leave me alone, please" you said on the verge of tears. He stopped and looked at you angrily.
"She said leave her alone" come an angry voice behind you. You immediately recognized Theo's voice and you were glad that he's here.
"Or what?" the guy asked and gripped you wrist harder.
"I'll kill you"
"Are you her boyfriend or what?"
"Yes, I'm. So, leave my girlfriend alone. And let go of her wrist" finally the guy let go of your wrist a little afraid of Theo but not too afraid.
"She's a slut" he gritted through his teethes.
That was the last thing Theo needed to hear, his fist met with the guy's face. Theo quickly gets on top of him and started hitting him several times. A few times the guy hit Theo, but Theo was the stronger, so he easily beat the guy up. When the guy was almost anxious Theo stopped and got up. He gently grabbed your wrist, not to hurt you and dragged you to his dorm. When you were in his dorm, you hugged him tightly.
"Thank you" you mumbled in his chest, and he wrapped his arms around you.
"No need to thank me, Cara mia" you got goosebumps at the nickname. He always called you that even though you're not dating, but you wish you are.
You were hugging him for a few minutes, but he pulled away. He grabbed you wrist gently to look at it. The guys fingerprints were visible on your wrist and it was already bruised. Theo gently grazed his fingers over the bruise then he lifted your hand up and pressed a kiss on the bruise.
"Let me take care of that" he said and mentioned for the bruise. You only nodded and let his lead you to his bathroom. He wet a cloth with cold water and put it on your wrist.
"Now you took care of me, let me take care of you too" you said and wet another cloth.
"Okay, Cara mia" he said and lift you up to place you on the sink. He stood between your legs and let you take care of him.
"Done. Do you want me to wash off your make up?" you asked, and he nodded. He gave you cotton pad and make up remover which you left here last time you slept over. You put some remover on the cotton pad and started washing it off. After it was done, you washed off your make up too. During this time Theo's hand were on your legs.
"Cara mia" Theo said after you were done washing off you make up.
"Yes?"
"I want to tell you something" he started and waited him to continue "I love you. I love you for years now" you were shocked to hear that but then you realized he only saying it because of the alcohol.
"That's not true. Only the alcohol speaking of you"
"Cara mia. I didn't drink alcohol tonight" he said slightly hurt because of your reaction.
"What? You didn't? Why?"
"In case I have to protect you. Or take care of one of the idiots of our friend group"
"So you mean it? You mean it that you love me?"
"Yes. I mean it. I only had enough bravery to tell you that now"
"Theo. I love you too" you whispered and grabbed his face to kiss him.
