Well yeah that's why I called them "borderline continuity" problems.
When they don't explain stuff, but just present it and force you to write the explanation for them it grates. I know it does because people on the board keep mentioning the things I mentioned as problems they have with Season 7.
And it is borderline continuity. I'll show you why.
Consider the Giles taking the Potentials out into the desert alone thing. That is a continuity error, because it's stated the potentials are under threat if they're not under Buffy's protection. You could say the First has gone underground after Showtime, so they feel safe, but they're still actively searching for other potentials to bring them to the Summers house for protection, so that doesn't fly. The potentials might be safe from the Ubervamp Buffy killed in Showtime, but it's never shown they are safe from the Bringers who are looking to kill them. They could no doubt come up with a reason why Giles would feel safe to take the girls out alone, but they don't, so it becomes an error. There is no explanation, and no hidden information given allowing us to explain it. It is a continuity error.
On the other hand consider something like how did Buffy know where to go to find the Guardians temple. At first there doesn't seem to be an explanation, but if you think about it, Buffy tells Spike something like it's a temple off consecrated ground. When she goes to find it, she passes out the gate from the consecrated ground to the crypt just outside of the cemetary that forms the entrance to the temple.
That's not an error, because the information is there if you want to look for it. On the other hand it is borderline, because it is something you would expect non-obsessed viewers to miss. If you want them to watch too, give them something they can make sense of.
In my opinion, if you don't, it becomes a "borderline continuity" problem.
