So, the show had Gwendoline Christie's Lucifer towering a good head over Tom Sturrige's Morpheus. But we know from a certain unpublished drawing floating around in the fandom, and furthermore from Neil Gaiman's answer to this ask that Morpheus had the means to be the one intimidating his adversary with his height. So why didn't he ?

Is it that Lucifer, a shapeshifter themself, would retaliate by making themself taller, which Morpheus would have to repond to by towering even higher, etcætera, etcætera, in a clash of egos that neither can win, unlike the Oldest Game ? Is that something that happened before ??

Or is it that Morpheus would rather play the humility card as he stepped into Hell uninvited and bereft of his crown he'd precisely come to retrieve ? Feign vulnerability (or feign to feign vulnerability so as not to let Lucifer on his actual vulnerability. Not that the Morningstar would be so gullible) so the Lightbringer would drop their guard and leave more chances for Morpheus to defeat them ?
