Thana's presence reminds him of the woman who would inadvertently cross his mind or would haunt his dreams. It was a woman he could not recognize nor does he recall ever meeting. But if they were complete strangers, then why would she suddenly appear in his visions?
He's willing to solve this problem, and the closest source to solving such a mystery is to start with the person who looks almost alike with the woman who has been on his mind, Thana.
Although he could assume that the woman in his mind could be Thana, he recalls that she has abilities to change her appearance. How that is possible is still a big question that would require thorough investigation.
Maximillian could only ask himself whether he could be out of his mind when he wakes himself up from staring at Thana as she does her hair. But it was too late, Thana had already caught his eyes.
