Penelope could conceal the dagger easily due to her wide sleeves. The crowd was massive too, so many did not notice the two women because everyone was concerned only about the disaster in front of them.
Samantha was starting to panic because she was afraid of hurting her child. However, panicking was a useless reaction at that moment and she had to calm down if she wanted to protect herself and her baby.
It seemed that she was not being overly suspicious when she felt that someone was watching or following her during the past few days. That person had turned out to be Penelope.
Judging from the situation, Penelope had been planning the attack for a long time now.
She decided to attack her at the exact moment when there was a huge crowd and everything was chaotic!
Samantha tried her best to keep up with Penelope's pace without confronting or provoking her.
