Bel merely listened to Harp speak, remaining silent. His ears twitched slightly. They had come to a stop at some point, he didn't even realize. He couldn't break his eyes away from Harps. It was almost like a trance and it actually startled the darker parts of Bel that someone had this kind of ability, especially against him. Maybe he had let his guard down, let it slip a small bit... it was enough room for error. But as the angel's words slipped into his ears, something else began to stir. He was not sure what it was exactly though, because he never felt anything like this before, at least not that he could recall. His chest felt a bit heavy, like someone had dropped an extra weight into it. A weight he did not want there, a darker thought crossed his mind in that moment. One that even startled Bel himself, which was a rare, unheard of occurrence.
Carefully Bel pulls a hand from his jacket pocket, swiftly raising it to grasp onto Harps, the one that had been placed upon his chest. One would think his hands would be quite rough, but they were somewhat soft and rather warm. His nails had grown slightly within the past few minutes, they now resembled small, rather sharp looking claws. Yet he was careful to be sure to not cut the angel's hand. His brows knit together as he tilts his head slightly, a few locks of dark orange hair escaping from his hood, a slight wrinkle of his freckled nose. A slight smile forms upon his pale lips as he begins to talk, his tone painfully soft sounding, maybe even slightly charming. He continues to gaze at Harp with now nearly black eyes that betrayed his soft smile and tone.
"It is truly sad to hear such sorrowful words from such a beautifully stunning pink-eyed angel. Claiming to be such an empty jar, but no jar is ever truly empty. All you must simply do is place it within the light, and then it may reflect all the colors of the spectrum on everything else around it." A soft chuckle escapes him. "But even the brightest of the sun beams falls pray to the darkness at night. Make a contract with me, Harp. Make a contract with me and I will help you fill your... 'oh so empty' jar and prove to you that no soul worthless. You can come to understand why my heart beats so sadly." He said it, Bel said it. A contract. Usually such things were made merely between a human and a demon, but it worked other ways too. And something gave Bel the impression that the other angels would not fully oppose to this, either. Harp, one who was 'apparently' worthless and a throw away, had managed to get farther than any other they had ever sent to be slaughtered. How had he gotten farther than any of them? Well, that was up for question, even by Bel himself at the moment. He did not 'do' contracts. Not with humans, not with anyone... At least until now, and he had only just offered.
It was interesting though, how the demon who held no interest in anything but power suddenly taking an assumed liking to a throw-away angel without wings. Without wings, Harp was mostly right, there was little point to kill him aside from the fact that he knew too much about Bel already. But something had crossed his mind, of just how amusing it would be to see how this played out. Would the other angel's be furious that this nothing was succeeding? But as Bel continued to stare at the angel before him... he realized he was not a 'nothing'. A nothing was a void of existence. Who stood before him was not such a thing, no. If Bel could calm him anything, it would be something along the lines of 'He who made a tiny impression upon a great demon'. Then again, that could be all the wrong wording. For a demon, Bel was quite terrible with words.
Bel lightly grips onto Harp's hand, eyes narrowing slightly as he continues to peer at him quite intently. Suddenly though he would twist his hand around the angels, attempting to twine their fingers together while pulling him roughly towards himself. His free arm would be out, attempting to loop around Harp as well. Should Harp have been pulled in as planned, he would easily find that it was not only the demons hand that was warm, but the rest of him too, even through his clothing!
