When a dosage test shows the sedative on the returnee matches Braxton's supply, they recall being drugged at the airport three months earlier. Their father wanted them to inherit the family factory, which Braxton managed and funded, so they doubt he'd betray them. Selling the factory's No.4 medicine would bring profits to the Ford family, so someone may have targeted them. Someone says, "Then let's make a deal": they'll find the attacker if the returnee serves loyally. With Mr. Lincoln due to try a sample, the culprit remains unknown and the returnee is forced to work for this new patron.
