Obi-Wan ran over to Natalia's now still body and used the Force to push Vader out of the way, he grabbed her hand and she gave it one last squeeze before her eyes glazed over, Obi-Wan closed her eyes for her and let her down, he didn't cry though, he had lost two of his best friends and he felt numb, there was no one left. "I will do what I must." He said, "You will try." Vader replied, Vader did a flip and attacked Obi-Wan brutally, he blocked his attacks easily, Vader obviously forgot who had trained him.
After a while Obi-Wan cut off Vader's limbs and let him burn, "I hate you!" Vader screamed, "You were my brother, Anakin! I loved you!" Obi-Wan said, now with tears. Obi-Wan bent down and grabbed Anakin's lightsaber, he pocketed it and took one look at Vader and he walked away. He arrived at the scene Vader had killed Natalia and he picked her body up and put her on the ship. She deserved a proper burial.
Natalia watched as clones took down more Jedi, as the Jedi Order fell, she was one of the many victim's of Order 66. But instead of a clone killing her,
She was killed by her husband Anakin Skywalker.
