Lubo Chapter 19 Page 37 (Patreon)

This conversation is happening to make a distinction between 2 things, but one of those things won't be discussed until a bit later. But right now it's important to know that Lubo's Alpha Form power DOES require a Moon Emblem as well as having the moon out in the sky.

As to who the "him" is, that should be clear soon. You won't have to wait for that "she" that was mentioned a few pages ago.
