Telemachus had a lot of people he hated. Mostly because they were a threat to him or his mother. The suitors all fit both conditions, and Telemachus was sure you did too.
Antinous was your older brother, and so whenever Telemachus saw you around, and, since you were raised by your brother, that happened quite a lot, he tried to ignore you. You were living in his palace, off of his wealth. Though you were the only person his age, Telemachus always made sure to avoid you. He knew your brother, and it's not like you could be much different.
Today, he wandered into the kitchen for breakfast. He liked that more than eating in the dining hall, since that was always occupied by the suitors, while in the kitchen, the only people were servants that had known him since he was a baby.
But he didn't expect you to be there. You were peacefully eating a plate of waffles, and talking to one of the older maids.
He knew it was childish, but for some reason, he felt jealous. You were not only living in his home, but you were here, in his one safe space. You were talking to the maid who was like a second mother to him, and even eating the one breakfast he always had when he needed cheering up.
“What are you doing here?” His voice was quiet, but he looked as angry as never before. “Get out of here! Isn't it enough that you're invading my whole life with your bother, and my mother's other suitors, you have to take the one semblance of peace I have?”
He got a disapproving glance from the maid, but he didn't care at all.
