Luna didn't check on him quite as much -- but his evening hours found themselves beholden to the Sun Princesses blue-flanked counterpart, showing her own measured, muted concern. So that was both surprising, and sweet... though she did demand more 'pets' each time she visited, which kind of defeated the point. Half the time, she'd even demand he come to her quarters for it. Wouldn't hear Arnon complain about it, though. Luna had this incredible softness to her fur. Princess Celestia's fur was more akin to... what you'd imagine the perfect pony fur to be, if absolutely well maintained to the umpteenth degree. Princess Luna's fur was almost otherworldly, and borderline  un-pony-like with a unique, plush texture that betrayed her cold outward expression. A thousand years on the moon apparently does wonders for the complexion.
