She's been thrown completely off-kilter by the revelation that she's the fabled Moon Princess they've been searching for, her life disrupted for a second time. He knows this, he can tell that it's getting to her, that in spite of all that she's glad to remember — him, the girls, the queen — that this is the last thing she wanted. That this life has suited her, and she's been allowed to live the freedom of normalcy and anonymity instead of standing in the spotlighted shadow of the throne she had been destined to inherit.

It's not the same for him.

For the first time in his life, he feels whole. He actually recognizes the sound of his own name and isn't questioning the merit of his existence. He may not understand why he was reborn alongside her and her court and still mourns the loss of the memories he's still missing, but he knows who is now. And after years of wondering who he was and feeling like Mamoru was the name of some stranger he was poor masquerading about as, it's a great comfort to finally feel at home in his own shoes.

Maybe Serenity was a completely different person in comparison to Usagi, but Mamoru and Endymion are one in the same.

He's always been Endymion.
