...... unlike spinel.... Raspberry's Transformation isn't permanent but she'll stay in her New form until 1: Angel comes back.....or 2: she stop's blaming herself and tries to Hold onto her hope that Angel will come back to the Hotel...or 3: she could just go back to earth with spinel, Anne and everyone else until she feels better....
so she won't stay like her mom forever....but She's in this new look because she blames herself for what happened during Ep8.... and it's taken a toll on her mental health....
oh and unlike her mom she doesn't have a heart-shaped gem on her body...(don't ask....why!)
so yeah.... that's raspberry in a nutshell.....
