[the book lands on his head, yes, and zack all but yelps and rubs at the point of contact—before looking up at sephiroth with one of those trademark hurt, puppy looks. all is well the moment sephiroth offers his apologies, and unable to find the amusement in the tone, rolls instead into a stage of worry.]

[sephiroth is always busy... so it's no surprise he is so tired he'd be dropping books.]

Aw, man...

[feeling guilty, he gets back up on his feet and puts a decidedly friendly hand to sephiroth's shoulder.]

Have you slept well lately? I shouldn't have asked you to come, obviously you're always busy—but do you ever stop and take a break? [there's no hint of sarcasm in his voice, as he obstinately leads sephiroth back towards a nearby chair.] Rest's important, buddy. If you want to take a nap I won't tell anyone. You know you can always count on me if you need a breather, right?

[zack is now Concerned.]
