Even though he had actually considered this possibility when the old monk appeared, he hadn't expected it to go so smoothly... Especially the moment when Kikyo said, "Let's go," he almost didn't react that the words were directed at him.
Because he knew that Kikyo might be prompted by this matter to make a firm decision, to pick up her longbow and arrows again, and embark on her journey to the Warring States. But he didn't hold much hope for her joining his team, because in the original trajectory of fate, the witch chose to walk alone.
Even when facing Inuyasha and others, she didn't choose to travel together... Although surely Himura Kagome's existence played a role, one can also see Kikyo's style of action from this.
—So it's not strange that Gu Mo would have such thoughts and doubts now.
—After all, Kikyo could completely set out on her own, just like the original trajectory of fate.
