"Greetings, Queen Searvale." Wil greeted the Queen without getting down from the cloud. As his status is equal to that of Cremia, the most he could do is to stand on the cloud, instead of continuing to sit down.
Meanwhile, Cremia also greeted him with a nod, "Welcome to the Kingdom of Searvale, King Time Traveler. I didn't expect your arrival, at least, in this situation."
"What can I say, Queen Searvale. I follow my heart. So, I'm quite unpredictable," replied Wil with a smile on his face. He understood the reason behind everyone's surprise but until he gets what he wants, he wishes to keep them in the dark.
At first, he thought even if Lupin's identity busted, he wouldn't lose anything but then, he realized that he loses favorability with the Queen because she might think he infiltrated their kingdom under disguise. The probability is low because he had helped her but still, the possibility cannot be ignored.
