Hushed Willows that's nice, that's a nice sentiment

The moment was carefully cherished and unbelievably perfect to the assassin, for whatever it was worth. He allowed himself to steal it, to live in it with her, as if time had stopped ticking on outside of them — never mind that very little of the patrol they'd been running had gotten done. The world was faded, easily tuned out background noise to Banner. His docked tail gave a few, unimpressive and easily unnoticed wags as she let out another rumble, a low, noise akin to a purr of pleasure lingered in the dark wraith's throat when he felt Banner nibble his jaw. The bites were small, felt but had the very opposite feeling of pain. Buchanan purled out a low, throaty word in Russian; and had been about to translate it when a bat screeched overhead. The sudden onslaught of high pitched noise caused his ears to perk, alert and then slick back to his rest against his skull cautiously when she gasped and abruptly tore herself away from him. He felt her absence, and though it was not particularly chilly with the absence of her warmth he felt the echo of her teeth nipping at his jaw before that, too, faded.

The moment had shattered at the heinous screech of the winged fiend. She moved quickly, oddly graceful he watched as she crouched low in a defensive position. His mercurial gaze watched her with cautious eyes, not unsure that she wouldn't attack him. He waited for her to cool off after she snarled into the darkness, to re-approach him but she did not. Though he heard her take deep breaths, Buchanan watched as her tail lashed violently behind her as she stalked away from him. Her body language sent off warning flags in Buchanan's mind: to exert caution. “Banner,” Buchanan called out to the Beta softly, rooted to the spot where she'd left him, knowing better than to attempt to approach her.

Silvern gaze assessed her, analyze her body language for changes noticable or subtle, the muscles of his shoulders tensing instinctively in preparation for possible aggression aimed at him.
