Original: Kagome frees Inuyasha so he can kill the centipede demon, but after defeating it, Inuyasha again tries to take the Jewel for himself.
Simplified: Kagome gets the arrow out of Inuyasha when a centipede yokai\/demon attacked her to get the jewel. When Inuyasha does kill it, he tries to kill Kagome too, to revenge on Kikyo (he thought Kagome was her), but Kagome can now control him with Kaede's magic by saying "sit!"
