Episode 98

Kikyo and Kagome: Alone in the Cave (洞窟には桔梗とかごめの二人だけ) is 98th episode of the InuYasha anime.

Plot
The episode begins with Kikyo being tricked by a demon posing as a young child lost in the forest and trapping her inside him as he appears to be a cave.

The following day Kagome gets angry at Inuyasha because he refused eating her home made food even though she made it especially for him even sweetening it so it wouldn't be too hot for him. She uses the Sit command on him several times and storms off on a "walk," as the others watch.

While out, she senses a jewel shard and follows the sense to the same cave entrapping Kikyo. She hears the child's cry as she approaches and enters the cave on her own. She finds Kikyo who is on the verge of death (because she'd nearly exhausted all her souls). Kikyo reveals the cave is actually the belly of a demon that only allows priestesses (or at least people who possess the power of a priestess) inside it and lures them into it to drain them of their power. She then insists she leave her behind to save herself, but Kagome refuses to leave her behind confusing Kikyo. The two then team up to find a way out.

Meanwhile, Inuyasha is anxiously waiting for Kagome to return, while the others wonder why he just won't apologize and tease him that maybe something happened to her to provoke him into looking for her. During this, Kagome and Kikyo are still trapped in the cave. Kagome remembers when Kikyo and Inuyasha kissed in front of her, while Inuyasha was under Kikyo's spell. Soon they encounter demons, but Kagome successfully manges to fight them off. They then approach the central core of cave/demon and Kikyo reveales to her that it is the demon's heart. Kagome fires an arrow, but nothing happens; sparking her realization that her spiritual power has been weakened during her time of being inside the cave. Kikyo begs her to escape and save herself while she still can, but Kagome refuses to leave Kikyo and insists they'll both find a way out. But then the exit to the cave then closes.

Back at camp, Inuyasha's fear for Kagome's safety runs out and he goes out to search for her. Kagome meanwhile inside the cave desperately thinks of how she can shatter the demon's heart and decides to combine a jewel shard to an arrow and shoots it, but it has no effect. Kagome then gives the remaining shards to Kikyo, who uses their combined power to fuse the shard together. With the new shard, Kagome successfully kills the demon, which dissolves into nothing but light. Now standing in a meadow where the demon was, Kagome recovers the shards while Kikyo's Soul Collectors come to aid her recovery, healing her.

As Kagome begins to leave, Kikyo asks Kagome why she didn't give up on her and how she could trust her. Kagome then says she couldn't answer her since she "doesn't understand it herself." Kikyo then asks why she would save her, "a dead person." Kagome then says, because "a certain guy they both know would be heartbroken if she [Kikyo] weren't around." As Kagome then leaves, Kikyo muses with a small smile, "Same for you." Indicating she is aware of Inuyasha's feelings for Kagome.

Kagome then finds Inuyasha leaning against a tree and happily greets him, surprising him due to their earlier argument. She asks, "You, uh, came looking for me?" To which he blushes before saying they should get going. As they begin to walk Kagome begins to say something, but Inuyasha ignores her. Kagome then thinks back to her time with Kikyo and then wraps her arm around Inuyasha's arm surprising him again, but he does nothing and they continue to walk with her arm around his own as the episode ends.
