"What do we have here?" Chase's breath hitched when he heard Isaac's evil voice.
The first thing he felt at this moment was fear then his instinct to protect Arrow and his baby at any cost which is why he did not hesitate, he didn't even realize how he suddenly broke the hug and pulled the vampire to hide him behind his back, forgetting the fact that Arrow is a bulky, powerful supernatural creature who happened to be a mass murder.
This move made Arrow blink multiple times in surprise as he looked down at the doctor's hand that was still holding his forearm tightly then he slowly diverted his gaze to look at how Chase was protectively hiding him behind his back.
He could sense how scared and worried Chase was for him just by smelling his distress up close.
This made him feel strange because vampires are emotionless creatures.
They are harsh and cold-blooded.
