The Doc lives in his own little world, doesn't he? I think his robots are just humoring him, which is bad because he flipped out in the 1970s and isn't too healthy in the current era.
From Metal Men #2 (June-July 1963)I've been waiting for him to address an unseen audience during his appearances in DC's 52 series. It would have been a funny hat tip to the Silver Age to have T.O. Morrow ask the Doc "What do you mean exactly, by 'keep those cards and letters coming'?"
