Looking good to outsiders, yes, but also a fig leaf cover in his own mind (the only one that truly counts) for the rottenness beneath. Doing this enables him to maintain the smug certainty that he is in fact a righteous person and most especially confirms he is better than everyone else (nevermind it is a completely ordinary thing to do*).
*though of course plebes don't have the mom & dad cash he does, so he is better because he can drop more. That's why he specified the dollar amount about the supposed poor Jamaican dancer - most people, even if they were weirdly going to boast about it (tmi, jfc), would just say "money.". What's that about liars giving too much detail...? Even if not a lie, it was important to him to specify it was $1000, both to emphasize how generous he was trying to be [did he ever say that they actually did succeed in giving her the money?], and to remind Kalea that he has that cash to drop and that she (maybe) does not.
It's pathetic.
