She looked over to Magnus who for a second had sadness in his eyes until he caught her looking. He may have not been the greatest father to the warlock, but he was still his father, he should be allowed to grieve.

Alec's eyes went from Magnus to Sebastian, his face lighting up like flames. "But that means his other form is still alive, no?" the cavern trembled as he shouted. He suddenly looked around in shock. Magnus was attempting to summon enough magic to do something, probably a portal.

"I hoped it wouldn't come to this, bind the creature with demon electrum" Sebastian chuckled wickedly. "It will only hurt badly it you squirm too much, stay still, don't use your magic and it won't be…too painful" He cackled, sending shivers down her spine.

Magnus fought back tears as they bound his wrists. Alec was kicking and trying to writhe out of the clutches of the turned shadow hunters. He was screaming Magnus's name while shouting curse words at Sebastian.

Her brother smiled amusingly and approached Alec.

No wonder your mother hates you, you and this warlock are disgusting beyond measures. You've ashamed your whole family. "Tell everyone here you're not gay and I will let the warlock go".

Alec studied him for a moment, thinking and then opened his mouth.

"What's the catch?" the other boy questioned, not meeting Magnus's eyes.

Magnus, through gritted teeth, looked over to Alec "Don't listen to him Alexander! I'll be fine, don't give in to him!".

As if the warlock said nothing Sebastian replied to Alec. "you must swear never to do unspeakable thing like this again and be a good boy and obey me".

"I-is there anything else?" Alec eyed him nervously.

"Oh yes I almost forgot, thanks for reminding me!" He winked evilly.

What was he up to?

"I need you to kill your sister" he said with no expression, looking at Alec, waiting for his reaction.

"What…your crazy if you think I would hurt Isabelle!" Alecs face lit up with shock and fury.

"choose. You sister or some stupid warlock that no one cares about!" Sebastian boomed.

"It's okay Alexander, everything's going to be okay" Magnus cried solemnly, not quite believing his own words either.

"How can u say tha-"Alec started to sob before Magnus interrupted him.

"Look at me Alexander, I love you, no matter what, you sister doesn't deserve to die" Magnus whispered loud enough for even Sebastian to hear which made him scowl.

"You don't either magnus!" Alec said, tears streaming down his face.

"I've lived hundreds of years my love, my time is up. You will find someone else, I want you to find someone else, you hear me?" Magnus said, with love and sadness all at once.

Seeing what these two were going through right now, made clary weak and want to break down but she knew she had to stay strong for everyone.

"I-" Alec straightened up carefully and looked over to Magnus "You've made me the happiest man alive, please forgive me, I love you no matter what Magnus Bane" The other boy stammered, tears mixed with the blood smudged on his cheeks, trickled down his face.

Magnus only nodded weakly, Clary could tell that, due to his age and what he had seen, he knew this had to be done and that it was the only way.

"I-do not accept your offer" Alec stammered, holding back tears and trying not to look at Magnus in case he broke.

"You hear that warlock? Your precious shadow hunter is giving you up, having anything to say to that?" Sebastian snarled.

"Go to hell" Magnus boomed roughly.

"Already been and it's not so pleasant" Sebastian said, for a second it sounded like his voice had a slight edge to it, like a serrated knife. "Now warlock, you work for me, take him to the dungeons".

This place has dungeons? So, he wasn't going to kill him yet after all, or was this just a trick?

Her brother's followers dragged away the helpless and weak warlock into the darkest part of the cavern which must have led to the cells. 'Hopefully' she thought to herself. Magnus was easier to obtain if he wasn't dead.
