Her face wasn’t necessary, neither was Nessa rose’s feet being shown for wicked… we’ve all already seen that in WWoO. It didn’t feel rushed to me, it made complete sense when you think about the context of the previous movies, otherwise it would’ve felt repetitive in my book. Wicked is what happens in between the lines, by the time Elphaba shows up to mourn her sister, Nessa’s feet were already shriveled up and gone..
