The guard was about to arrive there when Sophia received the call from her daughter. She explained to her the situation and asked her to return home instantly before the situation became unrecoverable.
Sophia couldn't go outside the lab, passing through the door. She thought the security guards who noticed the double-entry would catch him. Anna asked her to instantly hide somewhere.
Sophia went to the closed washroom and locked herself inside. The guard reached there and saw Sophia. He asked him to unveil her face at the moment.
Anna became trapped. She couldn't even say anything in front of all the people due to voice recognition. Trying to run was also useless because of the high security everywhere.
Sophia was listening to everything. She knew Anna's status very well. But, she didn't wanna invite a big hostility into her life. That would make her upcoming life challenging. So, she decided to take a risk to do anything to get Anna to escape.
