I liked how the Sun & Moon anime tackled the Stages of Grief with Mallow with her classmates, her Pokemon team, and her friends having to console and comfort her.
TO SUMMARIZE:
Denial/Anger: Mallow when she was young got visibly upset and mad at her dead mother, who kept saying sorry on-and-off and EVEN HATED HER FOR THIS, DIED.
Bargaining: Mallow awkwardly trying to find her dead mom.
Depression: Getting overly too depressed at this, and spent her next few years in this. EVEN CRYING UNCONTROLLABY IN DESPAIR WHEN SHE MEETS HER MOTHER AGAIN!
Acceptance: By the end of the series, she's moved into Acceptance for this, and lets her Shaymin (who may be a reincarnation of her) go into Sky Forme to reunite with it's friends.
