Author's Note: Hi all! I'm back, with a new PR Story :) This one is Dino Thunder, my first ever. So please leave some comments and let me know what you think

Summary: AU, During their last battle as Rangers, Dr. O is killed trying to save Kira and Elsa. The Rangers fight on, but when the battle is over, Kira can't forget the man she was falling in love with.

"Kira, get Elsa!" a voice called out through the dark bridge of the zord.

The yellow dino ranger did as she was told, shooting down the vines that held the woman up against a pole. Elsa collapsed into Kira's arms from sheer weakness, and Kira had to use all her strength to keep the woman upright.

She turned to watch as Dr. O matched Zeltrax point for point. The black ranger jumped and kicked his opponent straight in the chest, sending him backwards into the wall. Zeltrax slumped over, and Dr. O ran over to the two girls waiting for him.

"You alright?" he asked Elsa. The woman nodded her head. "Let's get out of here."

Kira let Elsa put some of her body weight against her own, and they started for the exit when Zeltrax jumped to his feet again.

"You're not going anywhere." With a swing of his sword, he launched himself forward at the three heroes. Dr. O jumped in front of the girls and blocked Zeltrax's attack.

"Go! I'm right behind you!"

Elsa started to move, but Kira stayed, watching as the two men in black caused sparks between their weapons. She had come to help, and that was what she was going to do.

"Kira!" The black ranger put his strength into holding Zeltrax's sword so he could look over at the yellow ranger. "Get Elsa out!"

Kira nodded and grabbed Elsa's hand before they both jumped out of the zord. Trent threw the last triptoid to the ground and let out a breath. "You got out!" Elsa released her hold around the yellow ranger and turned to watch the zord. "Where's Dr. O?"

"He said he was right behind us." Kira turned to watch the zord too. Seconds seemed like hours. It was horrible, watching the one spot where her friend and leader should have been coming out. What if something happened? What if Dr. O was hurt?

Kira didn't want to admit it, but something had been happening between her and the mentor of the group. She felt…protective of him. And more so than the father she had seen him as since the beginning of this journey. She didn't want to lose him. That was too scary to even imagine. But there was something that was fueling her urge to keep him safe, and she wasn't fully sure what it was.

"Kira! Something isn't right." The voice came from her helmet link with the boys, snapping Kira out of her thoughts. . It was Ethan, who was still up in the Mezodon. "Dr. O isn't responding. We don't know what's going on, and we can't attack if he's still inside!"

"Just wait! He said he would be…"

But Kira's words were silenced by a deafening explosion. All faces turned toward the sky as Zeltrax's zord careened to the ground, already on fire. The metal contraption hit the concrete and exploded, sending scraps of metal and red flames spewing across the city.

For a moment, just a split second of time, everything was silent. Then there was screaming. Kira felt like her mind had just been shrouded in fog. She fell to her knees, unaware that she had demorphed, as had Trent.

Tears splashed down Kira's face and landed on her hands, which were clenched against the ground. Trent tried to calm Elsa, who was bucking and kicking against his hold on her. Kira wanted to just slap duck tape over her mouth; this was not the time to scream bloody murder.

A minute later, Ethan and Connor appeared, out of their ranger suits as well. Elsa had fallen quiet against Trent's shoulder. They stood over Kira, glancing between her and themselves, trying to decide what to do.

Kira could feel them watching her as kept silent and still. She couldn't feel her legs anymore, nor the tears that were still falling down her face. The fog thickened, and the yellow ranger couldn't even make out if her own voice was saying the same word over and over again: no.

"There's a chance…" Ethan started, but his voice fell.

No one asked him to continue, and no one told him it couldn't be true. Kira slowly found her footing, and began to walk. Connor and Trent both yelled after her, but she only barely heard them, the explosion of loss still ringing in her ears.
