The most disturbing behavior we saw from Luke’s character was when he started snorting cocaine. He and Julian have it out for Sonny and plan to sabotage his coffee shipment with illegal drugs. Since this was such an extreme act for this character, what do you think is really going on with Luke?
Here are some theories that have been thrown out there by fans:
Luke was injected with drugs by the Cassadines
Luke is not really Luke and someone is wearing a Luke “mask”
Luke has been brainwashed.
