Forum:Flashback appearances

Should we be changing characters' last appearance dates to include episodes whereby they are seen later in the programme's history during a "flashback clip"? As far as I'm aware, these clips/characters are acknowledged within the Notes section of the specific episode anyway, and since the characters featured on these clips aren't credited within the episode itself, I'm not sure that we can say that this was a character's "last appearance". --Karen2310 (talk) 12:06, August 8, 2012 (UTC)
