| [Highlander II: just kinda odd that he doesn't mention it before or after this episode]
Perhaps he did mention it to Buffy before. Just because we didn't see it, doesn't mean that it didn't happen. For instance, I remember him telling Buffy that he likes to take long drives to relax, but we never saw him driving a car, at least not a civilian one.
Since Faith is there and not Buffy, she just didn't know about his Sunday habit. |
