One thing I noticed right off the bat about this investigation is that they devoted half an episode to it.  I mean, a full half.  Normally Ghost Hunters and GHI have been airing one investigation for about 40 minutes, and another for the remaining; the second investigation inevitably feels rushed.  This is perhaps primarily the fault of the post-production team at Pilgrim, but I thought it was worth pointing out that I thought they did a good job here by splitting the episodes up evenly.

That being said, why exactly did this investigation merit a full half the episode?  I'm just kidding, but seriously it seemed odd to me that they wouldn't cut this investigation down to a third or a quarter-episode when they have so often done that to somewhat dull investigations in the past.  Not that the investigation was wholly dull, it had its moments, but for some reason I just couldn't get that into it.  Maybe it was the leftover eye-rolling from the prior investigation's reveal, I'm not sure.

In any case, what can I say about this castle?  It had a couple of nice dungeons! Pretty much all the activity took place there.  First, Barry went into a smaller dungeon that looked like the epitome of the word "dungeon" — I mean, all it needed were some shackles hanging about 8 feet up on the wall and it would be exactly the sort of dungeon seen in every popular TV show, movie or cartoon that ever featured one.  He sat in this place holding the dictaphone up to his ear, I guess because he wanted it to record whatever he was hearing.

At one point we can hear an audible sound as Barry jerks hit hand — apparently he felt something hit the device.  Personally, I wouldn't rule out a big drop of water falling from the ceiling and happening to hit the dictaphone but that's just me reaching for a rational explanation, I don't have one that's a total lock so I'll definitely mark this off as a point of interest in the investigation.

In a separate dungeon, which seemed to be an enormous man made underground chamber, Robb and Dustin were trying to do EVPs but they kept hearing a ringing sound. At first Dustin thought it was his ears ringing (AKA tinnitus) but Robb was hearing it too, and before long so were we. The thing is, and this really annoyed me, it sounded exactly like feedback from a microphone.  I can't think of any reason why they would be carrying around speakers that would broadcast the audio from Robb's microphone and create the feedback, but this didn't sound "a lot" like feedback, it sounded "exactly" like feedback.

…and yet somehow this was thought to be potentially supernatural.

It blows my mind that no one so much as used the word "feedback" while experiencing it, reviewing the evidence or talking to the client during the reveal.  In fact, during the reveal Robb acted surprised that their host said he had been in that dungeon many times and never heard anything like that sound in there.  Of course not!  The most likely explanation was it was coming from the GHI equipment!  I don't think I've wanted to scream at the television or tear my hair out more than I did while watching the discussions of this sound.

There were two interesting EVPs — one of them wasn't even a sound but Barry, who I appreciate for his attempts to learn a bit of the native languages in order to do EVP sessions in the native tongue, had asked (in Afrikaans) any spirit nearby to make a noise, and in response there seems to be the sound of a door closing on the recording.  What makes this interesting is that according to Barry, not only did no one hear this sound at the time, but he had multiple audio recordings and this sound (which is not faint) only showed up on one of them.  I found this to be extremely intriguing, although we weren't presented with enough evidence to know if Barry is correct or simply mistaken.

The second EVP was while Brandy was talking — literally. It's one of those things that is a bit subtle, but once you listen to it a few times you can't mistake that it sounds as if someone begins to whisper something just before Brandy starts talking.  This could just be the human brain interpreting patterns where none exist, but I thought it was one of the more compelling EVPs I've heard in some time, despite not being able to make out a single word — that's how much I thought it sounded like a real whisper.  Of course, for all we know it might have been the sound guy whispering to the camera guy, so I still wouldn't get too excited over it.

When all was said and done, I think the feedback just overshadowed the investigation for me.  There wasn't much else to note, and while what there was seemed pretty interesting, GHI didn't deign to deem Cape Town Castle haunted.  I found this particularly odd since in the first investigation of this episode they labeled the Nottingham Road Hotel as haunted even after debunking half the claims and coming up with evidence of equivalent (to my mind) stature.
