I initially wanted to write everything exclusively from Stiles' or Derek's pov, but it feels like a lot of information is lost, so here is a small extra (like a short intermission?) from Kali's pov :
With every gush of blood, more and more energy left Kali. Her whole body felt cold, except for her throat, the tender flesh burning where the other werewolf had burried his teeth in, and her hands, which were drenched in her own warm blood.
She wondered if she were to bleed to death before her healing factor could kick in. Of course the wound would close slowly, it had been induced by an alpha after all, but this time, she couldn't even feel the beginning of her skin knitting back together. Was it because this alpha seemed to be even more powerful than all the others she had ever met? Even stronger than Deucalion?
In the end, it didn't matter anymore. Nothing mattered. Her mate was dead, just as the rest of her pack. Deucalion had the stones and would gain only more strength. All the emotions she felt, her love for her family, her hatred towards Deucalion and her wish for revenge, it all was pointless. She would die lying here, and she was ready.
She closed her eyes, eager for the darkness to overwhelm all her other senses, too. She was sick of feeling the hard, cold marble under her back or hearing the faint heartbeat of the twins, turning weaker with every passing minute. Even in her mind, she was still haunted by the unnerving tap tap of Deucalion's cane. Was she really imagining it or did the sound turn louder?
With a lot of effort, she pulled away from the darkness and blinked her eyes open.
Deucalion walked into the room in haste and obviously distressed. He rushed forward to the bomb he had left inside the room and tipped in a code to defuse it.
Kali looked at him with hatred in her eyes. This fucker had destroyed so many lives and now he could just get away with it.
In the corner of her eye, she could see the small gun that the banshee's assistant had used to protect herself with. Fucking big help that had been, for right now it's owner laid lifeless on the ground.
If Kali could just muster up enough strength to get to it.
She reached out her arm, her fingers scarcely touching the weapon's shaft, not even close enough to take a hold on it. But she couldn't let him walk away this easily. Gathering her last strength, she let her claws come out, the grown out nails finally long enough to pull the gun over. She took it in her hand and raised it slowly, her arm shaking with the effort.
Deucalion had defused the bomb at last. A trickle of sweat ran down his temple as he turned around.
"So, now where are the stones," he muttered to himself, but froze as he saw Kali pointing the weapon at him.
"What," he laughed nervously. "You gonna shoot me?"
No, Kali wanted to say, wanted to throw every insult at him, but her throat was to damaged to bring out any tone except for the rustling of her staggered breathing. Instead, she pointed the gun over his shoulder and aimed at the bomb behind him.
"No!" he yelled and jumped forward to wrestle the gun out of her hand, but she was faster and fired her last precice shot at the bomb.
Suddenly, her whole world burned up in a loud explosion and bright heat surrounded her body until, within a blink of an eye, everything turned dark and silent.
