A/N: Here's another chapter. Enjoy:))

Chapter 127: Sectumsempra

She was surprised by how quickly Draco's mood changed after they left the cupboard; merely a couple of minutes later, her ring turned a deep dark blue, with purple spots here and there. It didn't worry her though, being used to his mood jumps, so she went on with what she was doing, namely trying to figure out a way to glamour her scars without using up too much energy.

She was alone in the fifth years' dorm, so her books were spread on the floor around her. Being concentrated on a rather interesting page, regarding a pedant seeped in potion, she didn't notice when the blue changed to red. Soon enough though, a faded yelled curse echoed in her ears right before she felt prickling all over her chest and back and her stomach turned upside down. "Sectumsempra"

"No.."

She pulled off her shirt and a strangled sound escaped her neck as she fell to her knees. The skin was full of cuts, so many that it didn't even matter if they were deep or not. Hermione opened the door in that moment, just in time to catch the first bitter tear rolling down her cheek.

"Selene? What happened? Are you okay?"

"I'm, I-" she didn't get to continue, as her friend caught a glimplse of her torso under the half pulled shirt.

"Wait, what's that?" the girl's weak protests did nothing as Hermione pushed the fabric up and a gasp escaped her lips.

"Oh my God, what is this? Who did this to you?"

"Not, not to me. I think it's due time you found something out Mione. But not now, there's no time. I have, have to go. Just, I need to hurry before it's too late. l-"

The brunette rushed out the door and ran as fast as she could. She didn't really know where she was headed, but the bond somehow guided her. In her hurry, she passed Harry, but didn't pay much attention to that, or to the haunted look on his face, nor the blood smeared all over his hands. No, the moment when she started being aware of her surroundings again was when she entered the bathroom. There was a lot of water on the floor, but tinted red. In the middle, next to the sinks, the blonde boy was crying, twitching in pain every now and then, the potions teacher kneeling next to him, performing a healing spell, seeming to suck all the blood back inside the deep cuts.

"No! No, no, no, this can't be happening. Why is this happening? What's wrong with him? Who did this to him?Why?" she rambled, throwing herself to the ground, tears webbing her view, and she cupped his face in her trembling hands.

"Tell me!" she demanded from her godfather.

"I was walking down the hall and heard yelling. When I got here, Draco was bleeding out on the floor and your brother was staring at him, horrified."

"Wh, what? Harry was-he did this? But I, I" her clouded throughs cleared a little, just enough so a realization could bloom: her brother had almost killed Draco. Why? There had to be some reason behind this terrible thing. But she wouldn't ask him. If what Sev was saying was true, he was just as terrified of what he had done as she was.

"Now," Snape said getting up and dusting off his robes, ineffective in getting the bloody water off though. "I'm going to take Mr Malfoy here to the Hospital Wing. You should come to dear, and take a Calming Draught." He levitated a passed out Draco in front of him and took the girl's hand in his own, bracing himself for the reaction that Madame Pomfrey was most probably going to have.

Sure enough, the nurse took in the Slytherin's ripped button down, full of blood, and his and Selene's ravished appearance. The Gryffindor's face was red, her eyes were puffy and still full of tears, and after fussing around Draco, healing him and making the girl sit on a bed, she noticed blood dripping from her hands.

Turning them, she saw where it was coming from. Manicured nails were shoved deep into the skin, breaking it and most probably leaving bruises. But the fifteen year old didn't seem to notice, her eyes lost somewhere behind the nurse, a pained expression on her face and barely breathing. After forcing a Calming Draught down her throat, she seemed to relax a little.

"Merlin, I can't believe this is happening. Why would he do that? I know Harry has a problem with Draco but a cutting curse? Where did he even find that one?"

"I believe I have the answer to that question." Severus chimed in.

"What do you mean?"

"The curse, it was one I invented in my fifth year, Sectumsempra. But he couldn't have known about it unless-"

"Unless he has your old potions book, which he does. Is there anything else that is dangerous in there? "

"No, I promise. I was-in a bad place when I wrote that one, but everything else is safe. So that's why Slughorn has been praising Potter so much lately."

"Yes, it is. Although I do believe everyone is more comfortable without you breathing down their neck Sev. Is he going to be okay Poppy?"

"He is. It'll scar though." The nurse looked between the two teens with pity in her eyes.

"I know. It's fine. I'll go to the dorm now. I made a promise to one of my friends."

"Selene!" Madame Pomfrey called.

"Yes?"

"Make sure Mr Potter doesn't use that spell from now on. We might not be so lucky next time."

"I will."

Upon arriving in the shared room, Selene found said friend sitting on her bed.

"You've been gone for some time. And frankly, you look like you've been through a hurricane. Is that blood on your robes?"

"Yes it is. It's Draco's blood. Harry used a deep cutting curse on him, although I don't know why."

"What but, does that mean-" realization seemed to dawn on her and she looked at her friend with a combination of curiosity, sadness and suspicion.

"Well, I guess there's no avoiding it with you anymore and obviously no way around it so I'm just going to say it.

Draco and I are soulmates."
