At the museum, Janet Petty touches Barry and he floats up 10000 ft in the sky. When Ralph puts dampeners on Janet Petty, her power doesn't work and Barry starts falling. Ralph inflates his own entire body to make a giant cushion on which Barry falls and is saved unhurt. However, there are air flows in the open sky, even more powerful as one goes up that would take Barry sideways, so while going 10000 ft, Barry must have moved considerably horizontally, so he cannot fall right at the same point from where he had gone up.
It is strange that Null could open the CCPD/ S.T.A.R. Labs meta-human handcuff just like a child's toy.
