Ang really seemed to mean that oath, though. At the time that is--- though it's irrelevant now since the threat has lightened up. Jerimiah ought to take her back to the grave again, and shovel more dirt in this time. Maybe a lot more.
I thought at the end, was this all Ang's plan, getting Ben caught, stopping him only after he said the word "witch" but before he could say the name? To set up Vicki's conviction? Later, it doesn't seem so, though.
I guess no one really considered a honeymoon, even a stay-at-home one, under the weird circumstances. They seem to have moved on immediately to their stressful daily business, and they seem to sleep separately, from their first conversation.
