"I..." Will looked at his shoes and made a small face. "Tuck and Scarlet ain't been doing so well. And Marian... you know what she's been through. Rob's lookin' after Marian, and I don't even know how Much and Alan are holding up. And... and it's not like they can lift a hand against the Devil, so I thought... why add to everyone's woes?"
It was the truth. He didn't want to make himself a burden. He worried about Tuck being crushed under the weight of everybody else's problems, about sending Tuck back to the despairing place he'd been that night Much had told them both about Marcie. He didn't want them to have to carry the fear. But he frowned at the floor even after he lapsed into silence, and after a long moment, he added, "I din' know how they'd react. If any of 'em went into a panic..."
Will had managed to keep his panic firmly locked down by fixing his attention firmly on Clio and what she needed. He didn't need to be reminded how frighteningly justified the panic was.
