As they jump under the remains of destroyed building for cover, she gets to look at the ninja she pushed down.
It's Kakashi. She freezes, because that does not make sense. Kakashi... Kakashi is dead. He died months ago, when the three tails was sealed in her. Trying to rescue her
She tries to think for a moment, as the Kyubi roars and stomps around the village. Right the moment Naruto was born, in Kushina's most vulnerable moment, they had been attacked by a masked man. Minato had reacted so fast, that Rin hadn't had time to even understand what he was doing. He slapped a paper with a seal right on her forehead, and suddenly, she was back at his house.
Right as she heard the beast emerging. which meant Kushina was dead. She had started to run, with the intention of helping them, but she had run into someone on the way, as debris flew in every direction.
Child. Let me talk to Kyubi
As she went to pull Kakashi down again, before he did something crazy enough to get himself killed, she flinched at the voice of the tailed beast inside of her. This was the first time he addressed her without insults.
"Oh gods... The three-tails wants to talk to the Nine-tails," she said aloud, still grabbing at Kakashi's clothes.
