Milkshake and Ms. Huang

Theory: I think Milkshake sent Huang away to save her. He knows stuff is about to go down. He sees himself in her and wishes someone could have stopped him before he became what he is. Now, you're thinking, he assisted so jealous and seemed mean.

The tear in his eye was for her. I think he's come to respect her but like Natalie, who can't reveal what she's actually thinking, he had to operate under the fog of being.... well, himself. He's trying to tell her by acting that way. Telling her to grow up. He's saying that you're a child and it's adult swim, get out before you drowned.

Just a theory.
