He did learn something about the door, but Luka didn't consider it necessarily helpful. It certainly wasn't what he wanted to hear, which was definitely just the passcode.

The Wizard thus far has been even less helpful than the child, and Luka isn't particularly interested in accepting any mystery deals. He didn't imagine the Wizard was going to just open the door for him either.

When he's gotten a good distance between himself and the Wizard, he stops to lean against an abandoned building to catch his breath and reassess the situation.

"What the FUCK?" he shouts.
