In episode 15, Barry battled the King Shark that had escaped A.R.G.U.S. to kill Flash. Barry teamed up with John Diggle, Lyla Michaels and other A.R.G.U.S. members to get to King Shark and stop him. After much of a fight, A.R.G.U.S. is able to take King Shark in custody again. Later, however, a big revelation is made. Back on Earth-2, Zoom is revealed to be Jay Garrick. How Barry and the rest of them will deal with this betrayal remains to be seen.
