Lizzie died for the nether star so basically she IS the star And basically Joel keeps the star and gets mind controlled whatever whatever somenmagic death games whatever whatever but she basically influences not only Joel but the entirety of the world. Scar died because of Lizzie, grien was kept alive/revived because of Lizzie, and some of the other final members who died previously (like scott) were revived before the star was destroyed
please let this make sense When Joel’s base was taken from him the invaders destroyed Lizzie (the star) and since its presence was no longer active in Joel’s mind he intentionally tnt minecarted himself there’s some other stuff too. When fighting the wither a few open wounds on his body were caused to rapidly rot during the battle because. It’s the wither. But after obtaining the star the wounds “healed” but remained scarred in a way that reacts to the star JUST BELIEVE ME !!! this is canonical because I am a dirt block!
