Phoebe was stuck in a dilemma, having realized the sinister scheme of Theobold.
Not only did he reveal the fact that he had killed some of his soldiers, but he also revealed that these soldiers were spotted because of Mary.
Essentially, Theobold was causing a rift between her and Shi Tian's party, plus the fact that he wanted her to personally end these soldiers' family members as well.
The nefarious scheme of Theobold was well done, to say the least, if Phoebe had to reverse their role.
'This is why one should never cooperate with a wolf. They will bite anyone regardless if they're on the same side or not.' Phoebe cursed silently, blaming the higher-ups for agreeing to this.
The list of soldiers in the name was naturally people they trained for covert operations to spy on others.
Yet they were now spotted, and Theobold was practically telling her to personally kill their remaining bloodline with her own hands.
