And I'm impressed with the apostrophe action. Most people fuck that up.
Actually, he sort of did... per this grammar cite, since Kaos is a two syllable word, it should have had an "apostrophe s" at the end... Kaos's. Generally speaking, if the noun that ends with "s" is a plural noun, then just add an apostrophe, not an "s". Like "Look at all of the sailors' boats!" The boats belong to the sailors (plural: there is more than one sailor). If you want to write about a party given by Luke and Ashley Smart and all their children, write "the Smarts' party" (Smarts is a plural, then add the possessive apostrophe).
For singular names ending in "s," the Chicago Manual of Style adds an "s" after the apostrophe, as in "Charles's bike." If your work or assignment requires you to adhere to one convention or another, then do so. Otherwise, either form is acceptable so long as it is consistent throughout a single piece of written work. A common rule-of-thumb for singular nouns ending in "s" is to go by whether the word is pronounced with an extra syllable when in possessive form. With an extra syllable, add "'s.", otherwise, just add an apostrophe.
They do not call me the Grammar Wench for nothing...
