star wars - Did this character lose a limb in “The Force Awakens?”

Inspired by this answer which states limb loss as a recurring theme, I started thinking about the final lightsaber battle. After watching The Force Awakens the second time, I was not sure if

Kylo Ren

lost a limb or just lost his lightsaber. We definitely see

Rey slash at Ren’s right hand.

So knowing that context:

Did Kylo Ren actually lose his arm/hand?

Answer

There's no indication that Rey chopped Ren's hand off.

He was up again in an instant, but not in time to fully deflect a following blow from Rey’s weapon. He succeeded in blocking it, but he still took the full force of the strike against the haft of his own lightsaber. The weapon went flying into the snow. Unarmed, he raised a hand and utilized the Force to fend off one slashing blow after another, until finally her fury penetrated his remaining defenses. Taking a glancing blow to the head and chest, he went down, a prominent burn slashed across his face. Weakened, he reached out toward his lightsaber, trying to draw it to him.

and

Staggering back to his feet, his parry could not match the strength of her swing. It cast his lightsaber out of his grasp.

Ren extended a hand, calling on the Force to ward off her attacks. At first it worked, as she slashed into the iron shield of his will, but then her blade cut across his face. It burned.

He looked up at the girl whose lightsaber hovered over his chest. He shivered under the coldness of her stare. He who had been so eager to kill was not eager to die. Kylo Ren was afraid.

The girl withdrew from him.

and

She intensified her attacks, sensing more than seeing where he would strike next. Her blade cut across Kylo’s face before connecting with his saber hilt. Kylo’s weapon went flying into the snow.

Rey stood above him with her lightsaber raised. He was defenseless. She could strike him down right then and end it all.

Nor the script

Rey closes her eyes for a long beat. When Rey opens them, she is centered, fortified, and she POUNDS BACK, SINGLE HANDED SWIPES, hitting Ren's gnarly, spitting saber with incredible FORCE. It's so fast now, so furious, that Kylo Ren FALLS BACK -- She ATTACKS HARDER!

Ren gets up again but she HITS HIS SABER'S HILT -- HIS BLADE GOES FLYING OFF, TUMBLING INTO THE SNOW -- and she SLASHES AGAIN AND AGAIN AND HITS KYLO REN SQUARE IN THE HEAD AND CHEST. HE GOES DOWN, SUDDENLY A FEARFUL MAN, A LARGE BURN SCAR SLASHED ACROSS HIS FACE! He still reaches for his saber. And she could kill him -- right now, with ONE VICIOUS STRIKE!

But she stops.
