Terra was taught enough lore - and enough extra has bled through - that he understands the Graveyard's words, mostly. "Where are we? Is this - Kingdom Hearts?"

He raises a hand to reach out without realizing until he's done it that the world is too far away to touch, if he even could. "I'm sorry." He's learned a lot about waiting, and being alone, and this world has been alone for far longer with nothing to wait for.
