The above picture was a hotly used promo for the final season.

If you're a fan you might be aware that as I type this, we're three days away from the 20th anniversary of the premiere. Being the nerd I am, I'm planning to marathon all 6 seasons. So I'm excited with the show on my mind, haven't done a rewatch in a while, and it's a favorite. It's not my favorite finale ever, but I'm happy enough with it, never got the hate.

Anyway, I remember that between Seasons 5 and 6, at some convention or other, they first revealed that image on a giant screen, but they slowly revealed the characters, either solo or in tiny groupings. One of those things where everyone kept cheering. And I believe Locke was last and everyone went wild. I just want to watch it for nostalgia's sake, does anyone know where it is? I did a cursory youtube search with no luck, but I also don't have any more info than already stated. Thanks in advance :)
