Alex expected Joan to get better, especially after the person behind her condition had informed him that reminding her of the old things would help her regain her memory.
Was he playing with Alex or helping him? Alex had no intention of going back to Colton for help.
The only reason the bastard was alive was because of Joanna, and as soon as she was able to get along with anybody else who wasn't Colton, then Alex could freely give the order for Colton to be eliminated.
Joanna had fallen back into a state of unconsciousness after the doctors managed to stabilize her, but after the various test results, it was time for them to report their findings.
"There is a high dose of a psychoactive drug in her system," the doctor explained. Alex was furious for being deceived.
Colton had some guts in deceiving him about Joanna's condition. No wonder he insisted on being around the moment Joanna woke up.
