The audio levels thing will be related to the big 4 episode, and you'll definitely know it when you see it. You are getting very close, btw.
Also, just fyi, the 'connection between Ben and Glory' thing is a tongue in cheek reference to a particular bit of dialogue from later in the season. That you'll also definitely know when you see it.
And I thought I was asked for clarification.

That episode was...something. Nice follow up to Fool For Love (And whatever Angel episodes that aired at the time same), and I guess we needed some levity after the big episode. Spike is always a charmer, but I enjoyed seeing Drusilla back. There really isn't much to say about this episode other than a guy fighting over two women is kinda cliche, but because it's Spike and James Marsters makes things work, it was fun.
There was no controversial thing about that episode, by the way, Unless Spike being a stalker was the thing. That was a bit disturbing, seeing Buffy see all those pictures of her and the Manniquen. He deserved a punch to the face.
