I said the same thing. Gaurav is supposed to want to kill his father for loss of his child, hopefully it is not this one. So he could end up turning to SS for help. We need to see a bit more but Gaurav and Krishna could connect on some level. Notice during sagaii the camera kept showing Gaurav's response a lot when Krishna spoke to IG. He probably admires Krishna's guts to stand up to IG and speak his mind.
