Part of why the Librarian had asked the two of them to work together on this, was their skills could compliment each other. Trunks's skills lay in more obiviously physical combat style, but he also could sense life-force, and was durable. He would be guard and protector, and his own will and mind were stubborn and strong to help keep him focused.

A glance back, and Trunks nodded, as they set off through the halls. If Will opened his mind, that 'veil' over Trunks that was not his own was gone. And as they walked, getting closer to the area they were meant to be, he could likely see also that the 'veil' of Trunks own making was cast off too. It wasn't the active powering up, the preparation that Will had seen when they first met. But it was ready to be accessed, burning fire and will prepared to be used.

The lights were dimmer, the Library starting to seem like it was filled with Twilight. Bookshelves took on stranger shapes, and sometimes odd configurations as they moved. Things becoming dimmer, more chaotic.
