I believe it is Zoro who has the memory problems, not Sakazuki. I made Sakazuki aware of the whole crew's attendance in an earlier installment so his surprise wouldn't come into play. He's no happier to see Luffy than Luffy is to see him, but knows that attacking someone granted this kind of asylum wouldn't be wise.
