The parasites' living situation has changed drastically after the battle for Gran Crevasse. Zero Two's attitude toward them seems to have changed drastically, too.
You don't have to eat it if you don't want it.
لا حاجة لأكله إن كنت لا تريده
Dich zwingt keiner, es zu essen,
wenn’s dir nicht passt.
No comas si no lo quieres.
No te lo comas si no lo quieres.
Se non ti va, nessuno ti obbliga a mangiarla.
Se não gostou, não precisa comer.
Не хочешь — не ешь, 
тебя не заставляют.
