Does she slow him with her super power power or her super hot body power?
After reading the first page, it looks like Glider actually just wanted to break out Heatwave. She leaves her Brother strapped into the vehicle as it crashes through a barricade and plummets over the edge of a highway off-ramp. Sisters! Weather Wizard sweeps Heatwave into his car as he passes by the accident as Glider flies off to deal with another part of the plan. Captain Cold is saved at the last second.
I looked up the Pied Piper in my Who's Who from 1991 and was surprised to find that he was openly gay even back then. It seems he came out after reforming sometime after Crisis on Infinite Earths. So he was out of the closet sometime between 1985 and 1991. Very nice. Although I still think it's a bit weird to make the guy that plays flutes gay.
I don't know what Leonard did piss off his sister and Heatwave but I'm guessing it'll all come out in the Annual. Unless it's Pre-New 52 history! I wouldn't put that past DC.
Oh! I guess there was a little more to it!
I have to like this guy since he's the only super character I've ever cosplayed. As an adult, anyway!
