Whilst Earth-1s Patty Spivot may have been last seen on a train heading out of Barry Allens life, its good to see her Earth-2 incarnation get a shout out here. As Earth-2 Barry looks to get all techy in the search for Zoom, he namedrops Patty Spivot as being an expert in the field of meta-humans and mentions how her work is always of the highest standard. Oh, and also that shes a CSI, which just so happens to have been the career path that Earth-1s Patty left Barry in order to pursue.
