Doom Patrol Vol.2 #36 (1st Full App. Flex Mentallo)
After some time of waiting, Sara Furness is delighted to see her old friend Danny come back to her - a spectacle of sorts, given that Danny is, in fact, a living street. She rushes out onto his pavement to greet him, demanding to know where he's been. Most recently, he tells her via the letters of a shop-window's sign, he was in Berlin.
Confused, Cliff Steele helps The Chief catologue and organize the contents of the Doom Patrol Headquarters in preparation for their move from it. Cliff is confused because he has only just got used to this place, since the old headquarters was destroyed. He is also grumbling because, since Mallah and The Brain broke into the headquarters and destroyed his body, Cliff has had to use his old body, and it is highly unsatisfying. The Chief assures him that he hasn't forgotten his promise to get a new one arranged soon.
