>>50483952> Nihilego becomes LillieBecause Lillie's outfit was similar to illustrate Lusamine's twisted concept of 'beauty'. The outfit already served its purpose.
> Mohn is brainwashed by NihilegoBecause the story wasn't about Mohn eventually reuniting with his family; it was about him finding another life where he's happy
> the family reunitingBecause moving on from that disaster was the whole point. It's in the past; Mohn is happy with what he's doing, Lillie is finding herself, Gladion is...Gladion and Lusamine has finally stopped clinging to delusions and the past, and to accept whatever happiness her husband has now.
