Rikku, Yuna, and Paine went back to the tunnel where Tidus and Yuna was attack. Yuna may not remember but that was something that Rikku wants to forget. That event gives her nightmare every night during Yuna pilgrimage. Even though the nightmares die down, they're awakening after arriving walking to the hallway that leads to the room where Tidus and Yuna dies. Rikku stopped as her team looked back.
"Rikku, what's wrong" Yuna asked her but no replied.
"RIKKU?" Paine called out but still didn't answer. "This is the first time that Rikku EVER been quiet. That not likes her." Paine said to Yuna.
"I know. I don't remember being here, but it seems that something bad happen here, two years ago."
"Rikku," Yuna quietly called out her name.
"E lyh'd...hud oad...hud oad.." Rikku whisper.
I can't...not yet...not yet..
"What's you mean not yet?" Paine asked her.
"I can't face it again, no!" She cried. She duck and cover her face. "I can't face it! I can't face it!"
"Its better if we come back here another time." Paine suggests.
"Yea, that's a good idea." Yuna replied, and carried Rikku back to the airship, Celsius.
Back at Celsius, Yuna tried to get through to Rikku.
"Rikku, can you hear me?" Yuna asked here.
"Are you sure you weren't there during you pilgrimages?" Paine asked again.
"I don't remember. I remember escape from Bevelle but that just it." Yuna answers. Just than Rikku woke up and look at her teammates.
"Hey guys, what's up?"
"What's wrong with you?" Paine asked Rikku.
"Rikku, was you in a trace or spell?" Yuna asked.
"No, what are you guys talking about?"
"I mean when we were in that tunnel in Bevelle…" But Rikku face change.
"Oh…you don't remember, do you?" Rikku said in silently.
"What am I suppose to remember?" Yuna asked her.
"That dream…of Tidus and you dying…it wasn't a dream at all." Rikku answers.
The team was quiet.
"It was real?" Yuna asked.
"It was real…too real and I was there. It was something that I want to forget." Rikku started to cry.
"So it wasn't a dream." Yuna mumble to herself.
Rikku shook her head. "You did die there, during your pilgrimages…"

The team returns to the tunnel of the cave with Rikku in arms. Each step that Rikku, she remember her nightmares. Lost in her own trance she recalls every word that was said in that even.
It's a lot of words so I'm not recalling it.
When they got to the Macalania forest, Rikku stopped when she say a prayer for Tidus.
Please bring back Tidus, my secret cru...opps!" Rikku said covering her mouth. But it was already too late. Yuna and Paine knew, two years ago, she has a crush on Tidus too.
"That's all I remember," Rikku lied.
"I see. So that dream, it wasn't my dream. It was my memories." Yuna answers.
"Since than, I've been having nightmare every night during your pilgrimages." Rikku told her. "And now I'm going to have that again." Rikku begin to cry.
"Rikku," Yuna hugs her. "But you did save us. You save us both."
"I know but…" she begin silent.
"We all got scars from our battle, let heal them together." Paine announces "And beside, I miss the blabber mouth Rikku."
That makes Rikku laugh. Yuna turn to her.
"You're ready to go back?" Yuna asked.
"Yea…it's time to face my nightmares." Rikku replied.
And all in arms YRP return to tunnel, together.
