For now, Angor decided to keep Greya's whereabouts to himself without telling Toby. He did not know whether Greya was dead. Telling Toby about it would only put an unnecessary burden on Toby's mind.
Besides, if Toby learned about Greya's information and wanted to go looking for her in the Nightmare Realm, then how? Where was Haunt World? And was the plane tunnel toward Nightmare Realm still there? Any attempt would be futile. At least Angor was sure they almost had zero chance of finding Greya even if they teamed up together.
Hiding the information from Toby was the best choice at this moment.
Angor caught some restless sleep, troubled by the decision he just made.
