I regularly headcanon a 3H remake featuring Shez. At roughly the 2/3rd point the Church arrives to save Byleth after Byleth fought off an army and is losing against Epimenides, possessing Shez.

Epimenides quickly realizes Flayn will just keep healing everyone he's fighting against, so he Shadowflashes to execute her... only for Seteth to grab him by the collar, slam him onto the ground, and strike so hard with the Spear of Assal that the ground near him and 100 years away fractures, with Epimenides Shadow Warping away just in the nick of time and freezing up after realizing Shez was nearly obliterated. I just really want to see Daddy use his Crest to its fullest...
