MH blackmailed the senator that he's gonna expose him with the vid he took last time if he says anything, but TH also blackmailed him that he's gonna torture and kill his daughters if he won't tell him the truth bcs the senator was lying to TH at first (that SY is dead and he didn't see MH).
Also Taeseung's people were already there with his daughters, so yeah the senator had no choice but to tell TH everything.
How did Tae Seung find out that Minhyuk was the mole? What was the bait he mentioned?
