Bug: Arkham Trainer Cabal Quest

Attempting to complete the Quest was going well until the Trainer asked for me to go the Gargoyle that protects the Scarab Temple. I went to the gargoyle. Looked at the Gargoyle as I had done previously with other Cabal guardians. When I returned to the Trainer the Trainer never asked me a question as he had done previously. I assisted the aid of an immortal to see if I was doing something wrong. Attempting it several more times it was determined that I need to submit the situation here.
