"If his was more than just a vague ambition, if he was absolutely determined to discover the truth, there's no way we could prevent him."

Even if it sucks, at least it's real.  At least there are people who care and won't just leave.
At least it's life.
It's everything.

It's not a lie.  It may not be the truth the whole time, but it's not a lie.
And the truth is out there to be found.
