[Having not been around humans in peace as constantly as others, X is admittedly not an expert when it comes to sleeping patterns. He understands that, like Reploids, humans need to sleep to recharge their energy, and need to do so more often than Reploids do. What he still hasn't quite grasped, however, is that humans don't have anywhere near as close to a general set number of hours of "sleep," and that whatever they need might vary.
This is, of course, the reason why he doesn't notice the time when he slips into the master bedroom some time after waking up from his own recharge, noting the still figure on the bed as he moves over to the end.]
Otto?
