Menelaus wasn't his brother. The two while holding their own similarities, was much more reserved, even quiet compared to Agamemnon. She was as flawless as the stories described her to be. He didn't fawn at her feet right away, he still held his head up high to greet her like the Queen she was. To Menelaus, he didn't need the title to tell him. She was already his without the vows.
"What were you expecting?" He asked the young woman. Stories could paint a different picture, but for him he was in no way disappointed.
