It looks to me that Glen Murakami cleaned pages 58, 59 and 60 in this sequence; I cleaned the remainder. This is easiest to see because we both cleaned different panels of the same scene, B78. I suspect that all the pages in this storyboard cleaned with a Pilot pen (as opposed to a pencil) were cleaned by Glen which means he also cleaned pages 21-26 (Eternal Youth Act 2 Part 3). Glen was more artistically confident than I, hence his implement of choice was the Pentel Pilot. It was only in later episodes that I felt secure enough (and impatient enough with the pencil) to follow suit.
I recall looking at Glen’s portfolio at the time. He was obviously heavily influenced by Jaime Hernandez of “Love and Rockets” fame. Since “Batman, The Animated Series” was heavily inspired by “Mr. X” in its Los Bros Hernandez incarnation (and to a slightly lesser extent, Love and Rockets”), hiring Glen seemed like an obvious choice.
