On a "leave comments" page I see this in your code:

<div class="entryHeader"><span class="entryHeaderDate">January 31st 2008 @ 09:41 pm</span><span class="entryHeaderSubject"> - prologue.</span></div>

On the permalink, I see this:

<div class="entryHeader"><span class="entryHeaderDate">January 31st 2008 @ 09:41 pm</span><span class="entryHeaderSubject"></span></div>

So I would look at the code creating the entryHeader class and make sure it puts the subject in there.

It does look like the subject is showing up in the page title of the permalink view:

<title>adrenaline - prologue.</title>

So maybe you can copy and paste the variable from the title into the entrySubject area.
