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 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. She uses Sit command on him 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 apporaches 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 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 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. Kagome and Kikyo are still trapped in the cave which is actually a demon that lures priestesses in and drains them of their power. 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 while being in 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 desperately thinks of how she 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 asks why she suddenly so "talkative" before saying 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.
