Maybe he is already in love? He took her VOGUE Italia virginity (a bit off - but fashion is it's own world), and has used her alongside his long term favourites. Maybe he's just testing her. Her eyes are so powerful like a cute nuclear bomb, it makes sense to conduct careful tests and experiments before giving her a cover. Perhaps she's already done cover tries but they weren't right for the moment, or VOGUE Italia wasn't ready for the next stage of human evolution. Just like people who can't cope with Masha, they fear what they don't understand (is this x-men?).
