According to the Extella Zero script, what really happened was that because the path to Moon Cell core has a firewall which detects anomalies, it detected that a servant who's supposed to be dead after losing (Tamamo is week 4 enemy in the war and became MC's servant afterwards) is still around and stopped MC from advancing. So the MC and Nero has no choice but bid farewell to the fox. She even tried to fake some drama, crying big tears (literally just like she did in CCC true route) and walked away saying "I'LL BE BACK!".
