His Kind Is Rare.

When Arissa walked into Adele's ward with Nicklaus, Collins was already inside the ward with Jocelyn. He was staring at his sleeping patient - Adele. 

When the door pulled open, Collins turned to the door. The hospital report files in his hand lowered themselves. 

Arissa stood at the door with a smile while Nicklaus stood beside her, staring at the Doctor. Arissa walked into the ward with fast strides and enveloped Collins in a hug. 

"You came," she gasped, wrapping her hands around him.

Collins was stunned by the sudden hug. Somehow, his eyes met Nicklaus's unreadable ones. He stared away from Nicklaus and dropped the files on the floor. "I told you I'd always be a call away," he reminded, returning the hug to be more affectionate than mere friends. 

Arissa laughed and pulled away from the hug. She teasingly held both sides of his cheeks and a small pout formed on her lips.
