This was not up when I looked just a few days ago.
It wasn't up as recently as about 1am ET today, which is when I last checked, so it was only added within the few hours between the time I looked and you found it.
Not really sure how IMDB works, but the name is not hyperlinked like the other characters mentioned, so I am not sure what implications that may have. Maybe it's because it is not listed as ''Victoria Winters,'' which also, for some reason, leads me to suspect that she is employed in a local diner. Maybe it's the MaggIE effect.
Character names are hyperlinked if a character page has been created for them. If you notice, under the actor/character listing it says "Create a character page for:," then there's a drop down menu, and that's followed by a "Create" button. If whoever had added the name had entered "Victoria Winters," then I suppose it would be hyperlinked to the already existing page. However, it might be significant that they put Vicki rather than Victoria IF it's because they didn't want the name to link to the existing character page because the film's Vicki is different in some way from the previous Victorias (for example: the film's Vicki Winters is a waitress).
