I guess the opening VO is supposed to be from Maggie's point of view, and she still thinks that Barnabas is a vampire that should be exposed and destroyed.
That's something that bothers me... the voiceovers sometimes will state something is so when it turns out that that thing isn't so, and they knew it.... just because it's something they want us to believe at that moment. Like, the VO announced that Carolyn was dead when Barnabas was approaching the Collinwood front door, expecting to have to blab all to the family about having killed her through the Experiment... yet they knew Carolyn was standing alive just on the other side of that door.
Bad omniscient impersonal narrator, fwap on nose with rolled-up newspaper....
