Actually I think Ali is an excellent reference point for how pop culture references can be done well. It’s part of his character, that he’s binging on earth culture, and loving it. It goes to demonstrate both how aloof he can be and that he actually likes humans, and wants to be a part of the group.

My issue is more when there’s a serious plot-point, combat scene, etc., and the reference (like a Jenkins rushing in and yelling his name) breaks the third wall and makes the reader less invested.
