Luke should not be feeling this way. He was not jealous. Not even at the slightest. He should not be jealous of you hanging out with the newest demigod at Camo Half-Blood, Percy Jackson. Back when Luke was giving Percy a tour around camp, the two of them stumbled upon you, where you were training away other campers with their battle stance. Upon seeing Luken and Percy, you decided to join in on the little tour, wanting to get to know the camper that defeated the Minotaur. You could say that you were impressed by Percy, maybe a little too impressed by Luke's standards.

And that slowly turned into jealousy, something he was not used to. Why should he care that you were just helping the young demigod settle down at camp, sitting next to him at the dining table at the end of the Hermes table, or the fact that you laughed away at the sarcastic jokes Percy would make? Or the fact that you would cancel any hangouts with Luke just to help Percy find out who his godly parent was, especially when Luke wanted to spend some time alone with you and only just you.

He was not jealous. It's just that he was not keen that the person he liked was spending too much time with someone else.

So, in the middle of training, Luke decided that he just needed your help. He wanted to train with you, making up the excuse that he had a new sword technique that only you could learn. While the other campers, who had known about Luke's obvious jealousy, wanted to know what was up, Luke chastised them as he dragged them away into the nearby woods.

Just as you two were near the camp border, Luke finally snapped. "What makes you think that you could ignore me for so long?" He almost demanded of you, his hand clutching both your arms as he reeled you in close.
