Sorry it's been so long. I've got a bad case of writers block, but here's what I've managed so far. Hope you enjoy!

Varus laid down on their bedroll and feigned sleep.

'What did you say to the girl, Pallas?'

He knew that he could directly speak to the spirit through his mind. Usually he did not care enough about appearances and simply spoke out loud. Tonight he wanted some privacy.
Advice. Capture. Success.

An image of the Little Light handing Katarina over to shadowy figures flickered through his awareness. The Demacian spymasters, he suspected. Hearing words of praise from their mouths and watching the young girl smile. A fierce and sudden feeling of pride, a sense of 'we did that' pervaded his mind.
It reminded him of watching Theshan string his first bow.
Varus jerked in surprise. There was no falsehood, Pallas had told Lux to give Katarina to the spymasters. The second part was Pallas' own thoughts.

'You want to see her… happy?'

The presence in his mind went cold and quiet for a moment. A faint image of turning waves, a tumultuous journey, traced along the edge of his consciousness.

'You don't know, do you?'

A flicker of Lux's excited face, of the hand on their arm. The feeling of another person, after thousands of years without anything but the Pit, was almost too welcome.

He rolled over and scanned his surroundings. An urge that was not destructive or violent, it didn't make sense. Perhaps the spirit was trying to branch out, truly corrupt the Little Light. Varus became aware of green eyes staring at him. The Du Couteau woman always seemed able to find where his eyes were looking, even though he no longer had pupils. It was only when he met her eyes that a scarlet eyebrow raised.
Pallas might not have wanted to kill the Sinister Blade, but Varus certainly did. Such a powerful lap dog to the Noxian empire. The assassin was loyal to an ideal, not a person. It made her all the more dangerous. Surely Luxanna knew that the redhead would eventually escape. If not now, then later when the spymasters took custody of her.
If nothing else, the Summoners would be able to find her when she was next chosen to play. Katarina was a whirlwind of blades on the battlefield, extremely popular in the games. She may not have summoner spells to aid her out here, but she also didn't have magic inhibiting her attacks.

They could be dead as soon as they looked the wrong way.

Lux was ready at any moment cast a Light Binding on the redhead they had tied to the tree. It would only be another day or so before they reached the small town that had grown around the Institute of War. They would acquire a room there for a couple of days, long enough to contact the spymasters and organize handing over Katarina. It would be foolish to walk the Noxian into a safe house and release her into custody like that. Too easy for Katarina to slip away and gain information before retreating to the safety of the Institute.

What would they say? Would they tell Prince Jarvan of her success? Would anyone know?
She sighed and glanced between her two charges. No, she doubted anyone would be told of either success. 'A spy is like a good servant. Nobody should notice when they do their jobs well'.
It had been drilled into her as surely as any phrase from The Measured Thread. Though, no self respecting Demacian would recite from a spy manual as proudly as they would from their country's mandates.

She would be unable to use this adventure as a show of her usefulness to her parents. When Luxanna returned to Demacia it would not be to gratitude, but to more demands for an answer. Her answer.
All at once, Lux felt ill and rose from her spot against the rocks. She moved quietly, hoping not to disturb Varus, and sat by his bedroll. She didn't know if he had nightmares, but she could use that as an excuse if he woke and questioned her change of location. She needed some kind of comfort, and he was the best should get right now. Besides, she could still see that Noxian filth from here.
In fact, the red head was looking at her with a raised eyebrow.

Lux fought down a blush. Katarina had probably been watching her the entire time. Rather than look flustered she flipped her hair over her shoulder and subtly brandished her staff towards the other woman. Green eyes rolled dramatically at the Light of Demacia's fake bravado.

When Varus rose to take his shift he found a strange interaction going on.
First, Luxanna was now next to him. Surely Pallas should have let him know, the spirit always did when someone neared. It was similar to a cat hissing at would be attention givers.
Second, the two women seemed to be locked in some sort of staring contest. As his eyes went back and forth between the two he was sure that neither of them were blinking.
In fact, speaking of animals, they both very much reminded him of Gnar at that moment. Small balls of fury preparing to turn into something much bigger and nastier if left unattended.

He hadn't seen such hostility since going to his mother in law for her blessing to marry his wife.

"Little Light"

His gravelly voice broke the atmosphere and Lux jumped to attention, pointing her staff in his face. He paid it little heed and rose from the bed roll, reaching past the staff to guide her towards sleep.

"You have done enough tonight, Ms. Crownguard. Please, rest. I will watch the Sinister Blade for now"

The young girl blinked and rubbed her eyes before glancing back over to Katarina. The other woman was also blinking now and had moved her attention to Varus.

"Alright, but keep both eyes on her. We can die out here", The serious tone of her sentence was lost under a large yawn. Soon she was huddled inside the sleeping roll, seeming to enjoy the warmth that still remained in it.

"Do you really think they'll let you leave if she gets you all the way to Demacia, abomination?"

The smooth voice turned him away from his Little Light, back to the predator they had shackled. He moved away from the resting girl, hoping to allow her rest.

"No one dares to defy the will of the Summoners, Ms. Du Couteau. Not even the great Prince Jarvan IV. They won't kill either of us",

He stated. He had seen the power of the Summoners. Even Pallas was respectful towards them, submitted to their will in the games. If such a powerful spirit would bow to the Summoners, Varus was sure no being would lightly trifle with them.

Her laugh was cold and short. No joy in that exhalation of air, merely a tired jest nestled in mockery.

"I never said they would kill you. By the Strength of Noxus! They will try to take whatever it is Swain wanted from you. Now that they know you have something Noxus wants, they will do whatever they can to get it first"

He had already considered that potential outcome. Was sure that Lux was ignorant of her superior's desires. Perhaps she had guessed, she was no fool, but it would not stop her from performing her duty towards Demacia.

"My mission is not over yet. I have not been given the answers I was promised. Until the killers of my village are dead, no one can truly take my life"

He was not so sure he believed those words anymore, now that he had felt Swain's magic start to rend Pallas from his body. No doubt the Demacians also had powerful mages who could try similar magics. However, he did believe that such an answer would irk his captive and for now he was content to do that.

He was right.

"You are a greater fool than I thought. You have not killed me and now you tell me you plan to walk into the welcoming arms of your enemies",

Her growl of disgust made him smirk. She would find no ally in him. No sympathetic ear. Were it not in Lux's best interests, he would be cleaning her blood from his hands after ripping her heart out.
Pallas rippled. It was a pleasing image to them both.

I know not a lot happened this chapter. This is really just exploring interactions, not a very plot heavy piece. Soon they'll get to the Institute of War and then head on to Demacia.

Any comments are very welcome. I hope you enjoyed this chapter.
