A few days came and went.
Kagome begged her friends to keep Inuyasha in the dark. She didn't want him to worry nor did she want to explain her problem once more. She also knew that they couldn't afford to lose any more time.
After three years, the Shikon was slowly but surely coming together. Naraku was growing stronger, but the Inutachi wasn't just laying around doing nothing.
Within that time frame, unlikely allies were made, old disagreements were put aside, and new bonds were forged.
Trust strengthened to defeat a common foe.
Kagome didn't want to hold anyone back because of her predicament. So her resolve was to keep quiet.
