[Zero has more or less been enjoying their time here - even being out in the sun without any issue - and feeling more relaxed than he has been in quite awhile, if it's to also include home. Although he knows at the same time that he shouldn't wish for this particular prison to last more than just this one day left.
He's returning from having gone for something to eat, along with (having discovered he rather liked the first one) another Bloody Mary which contained more than just tomato to make it red. Something he's never considered trying - before (nor alcohol in general - out of being wary of drinking blood of unknown origins.
Prior to that, rather contrary to Lelouch, he was at the pool, leaving him still in his swim-shorts, as well as an open shirt. Not to mention a towel slung around his shoulders.
He just blinks at Lelouch upon crossing paths, then handing over the towel. Remarking on the scar isn't something he'll bother with. Maybe not yet at least.]
It probably won't help a great deal, but here.
[Ah. Yes. One notable difference someone might catch is the way his usually pale violet colored eyes are just slightly rimmed in a deep, even slowing dark shade of red. Most likely from the blood from his earlier drink. Which he really has no idea about. Oddly enough, too, as such a small amount of it usually has no affect.]
