The last thing I'd want to do on a book that's been well-received both critically and by fans is shake things up... but in the case of DOCTOR WHO: THE FORGOTTEN, life intruded and necessitated exactly that. Filling in for an Eisner-winning artist is never the ideal goal, but with issues 3 and 4, Pia Guerra had to step aside for some help. She'll be back with issues 5 and 6 (indeed, she actually did pages 21-22 of issue 4, too, one page of which is shown here) but needed to bow out of these two issues. For issue 3, Stefano Martino once again pitched in, and anyone who saw his work on issues 3 and 6 of our last WHO miniseries knows how good he can be. And then for issue 4, we have someone new to IDW and WHO, Kelly Yates, pitching in. As you can see by his pages shown here (first two are his, the last one is Pia's and should come with a slight spoiler alert), he fits in alongside her very nicely.
Meanwhile, the whole thing is presided over by writer Tony Lee, who never takes a day off... from drinking.
