Aizen, of course, noticed the eyebrow raise, and the start of a wince; he noticed nearly everything round him, after all... But the priority, of course, was the centaur -- or the Kentaurusu, as he would understand it in his own native tongue; he could deal later with this gentleman who was strawberry-coloured in hair, and thus obviously had a temper: a temper that he was hiding masterfully thus far! Aizen could commend that, in fact; he too had a dark side, if not a Temper, per se... And thus, he made a mental note to see about this gentleman, and where his loyalties lay, later...!
At any rate, he was concentrating upon the Centaur now, and thus it was he nodded gently in response to the explanation that the strawberry gave. "It's all true, I'm afraid, watashi no wakai musuko... This is a mysterious island, indeed... But if you like," he added quickly, moving to dominate the conversation, "I could help you find a place to build your new hut, here, as well as -- well, hopefully find your fae friends to sleep upon your back --your Yosei friends -- or I could be your friend, instead... And I could sleep upon your back -- if you wouldn't find it awkward, that is...!"
((Ooc warning: Aizen is actually fairly broad-shouldered, in the original manga, and thus... well... Ben Wishaw isn't that accurate a body model... But MAN, is he an AWESOME face model...! X-D <3))
