Oh, I adore the vamp twins to bitses, but I also enjoy seeing a more amiable and less driven Fuuma, but one with still plenty of personality. I also think it's painfully adorable how Fuuma seems to vie for Kamui's attention (he enjoys their rivalry) but Subaru is always there, doing his "ehem, boyfriend" stare. Fuuma's reaction to Kamui's statement just reminded me how cute they can be.

I think the twins thing is just Clamp's way of playing with the intricate relationship they already established for Subaru and Kamui before they put X on hiatus. It is nice to see Subaru slightly more reciprocal rather than "Leave me alone, I want to die." ^^;;
