Nostalgia Theater, a moment in time when we showcase something that has been showcased before. This edition is the comic Rainbow Wake by thestoicmachine. There’s a good chance if you’ve never read this comic, that you’ve seen pieces of it being used. The above is a prime example as I see that (and the frame before it) all the time.
The series is 5 pages, was 4 with a super secret ending. It was featured in basically the early days, the first page coming out back in February and from the looks of things, ended the next month. All 5 pages behind the page break.
