Clabastian or Clace?

Clary and Sebastian

     "Where is Jace?"
Sebastian glanced up his book and rested his eyes on his sister. She was standing in the doorway in nothing but a silky nightdress that barely covered her underwear, her arms crossed defensively.
        "I sent him away to entetain himself. " Sebastian said idly , turning a page in his book.
        "Why?" Clary demanded curiously , "Where did you send him?"
  Sighing heavily, Sebastian made a big show of marking his page and closing the book, setting it down on the table and getting to his feet, leaning back against the wall. He knew Clary was more desperate to know where her darling Jace was than she was showing, and he was going to tell her when he wanted.  He would have told her anyway, but at his own accord, he was the one in charge here.
        "He is allowed to do whatever he may wish as long as he stays away from here." Sebastian said at last, "I wanted to spend some quality time with my little sister."
As he looked her up and down he couldn't help but dab at his lips with his tongue, smiling appreciatively at her choice of clothing.  So much of her pale, creamy skin was exposed and with her flame of red her hanging tousled over one shoulder she looked so desiderable, so heavenly. He saw her shudder at his words and appreciated it greatly, he liked knowing that she almost feared him, that she was frightened of the power he held over her, because he was her big brother and she was his propriety, he could do whatever he wanted and she would have to deal with it. Taking his sweet time, Sebastian started to walk towards Clary with such a pace she could  be overwhelmed in anticipation, worrying about what would happen next. When he came to and stop right in front of her, he leaned down to whisper în her ear:                                "We're going to have a whole lot of fun, Clarissa."
