Threat
There really was no need for threats; it would have been ridiculous for either one to use threats against the other as one way or another, as it would always be ignored. But no matter how futile or hopeless it was, both the blonde and informant would still continue to threaten the other – whether it was for their own entertainment or a way to vent their anger on the other.
"Shizu-chan, do you know something?" The informant spoke into the phone, listening to the many chatter from the other line before a grunt which questioned him.
"What?"
"If you ever leave me, I'll kill you." Izaya hummed into the speaker. As many times as he told the blonde such words, a part of him couldn't help but to worry that Shizuo would leave him one day and belong to someone else. "Break you down so hard that you'll only have me to rely on."
"HUH?" Shizuo's voice boomed – something which laid between a growl and a yell, but neither of each. "What the fuck are you talking bout? Shouldn't it be me saying that?"
At that moment, Izaya wondered if the blonde had the same feelings, emotions and thoughts running through his mind. Maybe he did, maybe he didn't.
"Yes, yes, Shizu-chan. I'll be hanging now, see you tonight." Izaya was sure the blonde was about to say something, but he hanged before letting the blonde say what were on his mind. Whatever it might have been, the informant would prefer if it stayed in the blonde's mind.
"One day...he'll really be gone, won't he?" Izaya murmured to himself as he wore a frown. But it was quickly replaced with a smirk. "Maybe...after all, even monsters can die." The informant said as he took a quick glance to the chessboard, before he chuckled softly to himself, turning back to his computer.
