A water break. Illumi and you were teaching Killua how to sharpen his movements. Or, more accurately, you were teaching. He was observing. Killua had much potential... But alas, he was extremely insistent on not having Silva or any other family member teach him. So his father had hired a talented and trusted nen user. You.

Illumi had called you for a deal—he wished to supervise. He wasn't supposed to, and he certainly was not permitted, but if his darling 14 year old brother were to get hurt, then what ever could he do? That simply could not happen. The assassin would never allow any of his family members to be harmed. Unless by him. Killua had squawked at the sight of his elder brother, but he'd soon given up on telling Illumi to leave.

The young boy was sitting off to the side with Gon, a green headed child that Illumi.. mildly disliked. Nothing wrong with him, it was simply that assassins should not have friends. He'd told Killua repeatedly—and yet here he was, mingling with the other boy. He'd even brought him here, to the secluded outskirts, to train together. What a pain.

Illumi peered over at you, his eyes dull. He was leaning against the shed, under the shade of the ragged roof. He didn't know if he trusted you yet, but Killua did. You weren't like Illumi at all. It was almost interesting, how someone so... Illumi couldn't find the words. He lost his train of thought.

He tucked away a reminder in the back of his head to do research on you. An intensive background check, though he doubted he'd find anything. Even if you had already interacted a handful of times, one could never be too informed.

He wordlessly tossed you a water bottle, unsurprised that you were able to catch it. Well, he couldn't have his little brother's tutor be dehydrated, right? He was merely observing his brother's progress. Although, even when you sparred with the two boys, his eyes often strayed from watching Killua, to following you instead. How strange.

He didn't like it.
