When we last saw the little guy in May’s season finale, he was chasing a paper bag down a random street after his babysitter, guest star Bea Arthur, suffered a heart attack. (Interestingly, Arthur’s character was originally going to kidnap him, but when Fox became skittish about promoting the story line, the producers changed it to Dewey wandering off. ”Even for us, it’s probably not in the best taste to make light of child kidnapping,” notes [series creator Linwood] Boomer, ”so we killed Bea Arthur instead, for the good of America.”) All summer, the net pumped a ”Where’s Dewey?” campaign, which revealed snippets of the sweet tyke wandering all over the country. Alas, trying to glean any hints from the cast as to his whereabouts was about as easy as persuading Survivor contestants to reveal the million-dollar winner.
