Sure, as long as you ignore the fact that Iax was getting dragged into the Garden (or the Garden was getting dragged into Iax, probably both tbh) because of what Ku'Gath and Mortarion were doing, and that the comparison b/w Lucius and the Emperor is hilariously idiotic to begin with, and the fact that ... a Custodian turning into Lucius has nothing really to do with the scene that did happen? But don't let that get in the way of the salt-mobile.
Pretty much all of the top 100 posts in that thread are better than...whatever that is.
