Flash, Vol. 2 #170A

When the police ask Wally to assist two of their own, it brings him back into contact with not just one, but two of his ex-girlfriends. While he's working to bail out Fred Chyre and Julie Jackam from a murderer, he also encounters the intervention of Magenta. After counseling, she's attempting to use her powers for good.

The criminal they're trying to apprehend, however, detonates a suicide vest giving Wally scarce seconds to save the police officers. And as she does so, she tells him that this is all for the Flash.
