In the fleeting moment that Northern was busy copying his talents, Cal had materialized behind a White Walker.
And with a casual flick of his wrist, Cal punched through the creature's back, his hand emerging from its chest, fingers clenched around a still-beating heart.
The Walker's eyes widened in shock, its body convulsing as it realized its fate.
Cal withdrew his hand, the heart slipping from his fingers to fall into the snow, steaming in the cold air. The Walker crumpled, lifeless, before it even hit the ground.
Another Walker, a female, seeing its comrade fall, roared in rage and charged at Cal, swinging a massive hammer.
Cal's eyes gleamed with amusement as he ducked under the blow, his movements fluid and effortless.
The Female Walker's momentum carried it past him, and Cal spun, delivering a brutal kick to the back of its knee.
The Female Walker dropped to one leg, and Cal's hand shot out, grabbing it by the back of the head.
