Déjà vu Time: There is now a fan campaign to get Michael back on Breaking In. "Could you all Tweet/Facebook him [Michael Rosenbaum] to ask [VERY NICELY] if he would make an appearance in the final episode. - Please no Threatening comments like some VERY rude people did when Smallville Ended. Rememeber... we don't Bully those we are asking a favour from!"
(If the timing lines up & he's not too exhausted from filming Old Days, he might do it. He's been getting as many tweets about Dutch as he did about Lex!)
