  urlLink Kakashi just used an illusionary technique against Sakura, which made her see Sasuke all beaten up and bloody. She fainted, and when she woke up and walked around, she saw Sasuke in the ground. (Kakashi put him there. ) So, she just saw his head and thought it was severed, so she fainted again. When she woke up and found out Sasuke was all right, she hugged him in relief. I love how Sasuke exclaimed, "Stop!! Don't hug me!!! " Gave me quite a chuckle.
