If you follow the link, you’ll notice that the official version of this comic is abridged for publication. How do you get to see the larger versions, plus added commentary by Tom Tomorrow? By subscribing to “Sparky’s List“. Not only that, but you receive it several days before publication (although we members of the list are sworn to secrecy until the official comic is published).
By the way, I love the reference to Doctor Who (and The Silence) at the end of this comic. It is especially timely since the new season of Doctor Who just started this weekend, right between the two conventions. How quickly will we forget?
