In case you haven't heard, Granger did not hire a The Flash. Identical twins Jared and Jacob Olivas are BOTH police officers for the city of Granger in the lower Yakima Valley!

Jacob and Jared grew up in Zillah and wanted to be police officers their whole lives.

Jared was hired first and Jacob remained on a list of desirable applicants until an opening was available.
Aside from looking alike, they don't have any special telepathic powers. One doesn't sense it when the other is in trouble. They still have police radios for that.
