Are You Now Or Have You Ever Been - S2-E2
Continuity mistake: When Angel hides the bag of money up on the shelf in the basement, he is not wearing glasses. However, in the close up shot of his arms and the bag though, he is.
Other mistake: Both times we see Lindsey shaving, once before his hand transplant and once after, his reflection in the bathroom mirror isn't in fact a reflection. He is wearing a bracelet on his left wrist, but in the mirror it is on his right wrist.
Disharmony - S2-E17
Continuity mistake: In some of the shots in the scene with the red bird, it is raining and in some shots it is not.
Revealing mistake: When Wesley accidentally turns off the power, the room briefly goes dark, then lights up with moonlight/streetlight from outside. In the real world, that light would have been visible the whole time in the background. (00:01:45)
Revealing mistake: Just after Angel kills the quan-eyed demon, he exits the room behind the smashed mirror. On the widescreen DVD you see Angel's reflection in the mirror to the right of the smashed mirror (even though vampires don't have a reflection). (00:03:40)
Character mistake: In this episode, Gunn wonders how he could have lived in Los Angeles all his life without knowing about all the "weird ass stuff" going on. But flashbacks in "Double Or Nothing" show that he knows demons exist there.
Blood Money - S2-E12
Continuity mistake: During the charity event when it shows the birth year and death year of Holland Manners, it suggests he was 49 years old when he died. But in an earlier episode, he attempted to sacrifice his daughter for his 50th birthday.
Disharmony - S2-E17
Continuity mistake: When Angel pulls Cordelia aside and says that Harmony cannot work with them, a man in the background walks past in the shot of Cordelia but we never see him walk past in the shot of Angel.
Other mistake: Later in the day when Cordy has recovered a little and is cleaning, Angel says something about seeing a reflection in the picture. We hear Cordy say, "What do you want," but the subtitles say, "What do you what?"
Answer: Due to his epiphany, Angel basically had the 'true darkness' he worked so hard to reattain ripped away from him, like his soul was after sleeping with Buffy.
