Sarah and Lilith noticed Lucas was coming back to them, and ran towards him. Sarah was in tears as she jumped towards him for a hug.
"I-... I was so worried!" Sarah sobbed.
"I told you, there was nothing to worry about." Lucas smiled brightly and patted Sarah's head. "Come on, let's get you a dress. Shall we?"
"A dress?" both Sarah and Lilith exclaimed in unison.
"A DRESS?!" Lilith repeated. She couldn't believe that Lucas, of all people, would still think about getting Sarah a dress. "Who the hell was that guy?!" she grabbed Lucas's collar in anger. "He was a demon, wasn't he?!"
"No... Uh... How do you know about demons?" Lucas raised his brows in genuine surprise. He couldn't understand how Lilith could have a knowledge about the species that were never introduced to the public.
"Why does that matter?!" Lilith frowned in anger at Lucas for not getting to the point. "Tell me, why were you making a deal with a demon?"
"W-What are demons?" Sarah gazed at Lilith curiously. "Is it like a monster or something? Is it dangerous?"
Lilith looked back at Lucas in shock. She forgot demons hid themselves amongst the humans.
"The ones in power keep knowledge about demons secret from the public. Lilith." Lucas sighed. "How did you not know that, despite knowing what demons are?"
"My father told me about them." Lilith replied coldly. She wasn't lying, as Isaac indeed taught Lilith many things about many mortal worlds; that includes the hell and its native race of demon-kind. But of course, Lilith knew that demon-kind was hidden from the society, it simply never crossed her mind that Sarah wouldn't know about it.
"But who is your father? How does he know it?" Lucas crossed his hands on his chest.
"Isaac. Isaac Gold." Lilith crossed her arms as well.
"I never heard of Isaac Gold." Sarah muttered to herself, but both Lilith and Lucas heard it.
Lucas scratched the back of his head, as he remembered the last name 'Gold'. He just couldn't grasp it where he heard this name, 'Isaac Gold, where did I hear this?' Lucas thought to himself. He stared at Lilith and sighed.
"Look. If you know what demons are, then you know emotionally and mentally they are no different from humans." Lucas made a quick smirk before he added: "and there was nothing to worry about. We're all fine, aren't we?"
"Fine?" Lilith scoffed. "You just made a deal with a demon!"
Sarah continued looking at Lucas, as she couldn't understand what was going on. She thought 'What kind of deal did Lucas make Lilith is so furious about it?'. Sarah gazed at Lilith, who walked towards her and grabbed her hand.
"Come." Lilith dragged Sarah towards Lucas. "Tell her what is a deal with a demon."
"H-Huh?!" Lucas had an expression like he had seen a ghost. He was nervous to see how Sarah will react, but he also didn't want to make the situation worse.
"Umm..." Lucas thought of everything he should say, but in the end, he told the truth. At least part of it. "I made sure that Dorian would stop killing people."
"Uh... okay?" Sarah raised her brow and threw a gaze at Lilith, who crossed her arms in annoyance that Lucas was not telling all the truth. "It's good... Right?"
"Yes, Sarah. It's good as long as Lucas keeps up with his part of a deal." Lilith gritted her teeth. She couldn't hear what Lucas was talking about, because as the two creatures made their pact, their voices turned unrecognizable and spoke in a language she never heard of. "What is your part of a deal, Lucas?"
"T-That..." Lucas stuttered. "That..."
"That?" Lilith cut Lucas off. "What is it?"
"That is not your business." Lucas' voice was shaky, which made Sarah gulp hard. Suddenly, Lucas kicked the ground in anger. He yelled out as he pointed his finger at her. "I am tired of dealing with you! What the hell is wrong with you, Lilith?!"
"W-What?" Both Lilith and Sarah gasped in shock. They never heard Lucas raise his voice at them, but this time, this was serious. However, Lilith clenched her fists in anger before screaming back at him.
"Don't you dare talk about me like that!" Lilith screamed at Lucas. "Especially when you're the one who messed up!" she grabbed Lucas's collar again and pulled him closer. "All I am asking is to know what deal you made, so maybe me or my father could fix your bullshit!"
"G-Guys? S-Stop." Sarah quickly interjected between the two. "Please..."
The three stood in silence for a moment. Eventually, Lucas sighed. He took a deep breath and calmed his heart down. Looking back at Sarah, he bowed. "I'm going home." He started to walk away.
"Y-You son of a..." Lilith's eyes widened in anger. "Why are you acting like this?!"
Lucas stopped walking and started laughing. He could barely hold his anger, which he released in a sarcastic laughter.
"B-Because... I AM THE ONE WHO OFFERED A DEAL!" Lucas turned back and yelled. "I AM THE ONE WHO MADE HIM SIGN A DEAL WITH ME!"
"Just tell us... What was the deal you two made?" Lilith pleaded with Lucas, but he just shook his head.
"Sorry, I have to go."
"Lucas! WAIT!"
The girls screamed and wanted to follow him, but he turned back and told them.
"If you follow, I won't ever talk to you two ever again." Lucas frowned. "Especially you, Lilith. You're on a VERY THIN ICE."
"Stop, Lilith, let's not push it!" Sarah grabbed Lilith's hand. "I don't think I ever seen Lucas so... I don't even know what this is."
"He is worried." Lilith made an eye contact with Lucas one last time before he walked away. "I think he made this deal to protect us." she bit her lip in anger and clenched her fists so hard, her nails dug into the skin, puncturing it.
"Didn't he say that he made a deal to protect innocent people?" Sarah asked.
"Yeah, but..." Lilith nodded. "But..." her voice trailed off. "I don't know. I couldn't hear it!" Lilith cursed the deal between a demon and an angel. Whenever a divine entity like a god, a demon lord or an angel makes a deal with someone, no matter who the third party is or what is their race; no one other than the ones who made a deal could comprehend the conversation. Even her father won't know what the deal was.
"I guess we'll find out if Lucas decides to talk to us again. Let's give him some time" Sarah smiled stroked Lilith's purple hair.. "Come on, let's go home."
