The shelving encompasses Roland, all that he is. A man that never switches off, always has to get out his thought on this and that, every note and thought making their mark. If Roland was to leave, he wouldn't be erased from the train - not in here anyway. We're always trying, as he'd said.

Tidus wonders if it's a reminder for that, an emphasis. And he wants to ask the meaning, but doesn't even realise that Roland's walked back to the transgate until he turns his head to look at the guy, a word on his mouth. Then he's scrambling back over, curiosity now something new - or, really, still yet to be answered.

"Where're we going?" He heard about cabins, but- "You forgot something?"

The books? Is Roland leading him around to help him take back his library books?
