Never Again:
Jack stood at Sam's infirmary bed. He hated this position, waiting for news of life or death; not being able to take her place.
The strong possibility of death lived every moment with them, but Jack knew that death wasn't just physical, but emotional, spiritual. Sam had brought Jack back to life before. Not even knowing, because of her, he breathed again.
While the monitor broadcast Sam's fight, Jack encircled her hand in his. Jack knew if Sam didn't make it he'd be the living shell of a dead soul.
He wouldn't survive.
Not without Sam.
Never again without Sam.
