Tyler did not directly tell Heloise that the "Earthly Ghost" was a member of the evilkind, a villain.
Following the same strategy as before, Tyler pretended to be ignorant of the true identity of the "Earthly Ghost", using the guise of a "friend" to broach the topic of Heloise's conversations with the "Earthly Ghost".
"Heloise, the reason the Benevolent Deity 'imparted the knowledge' of the 'Earthly Ghost and the Shadow Serpent Society' to me is with the intention of saving the 'Earthly Ghost', who has lost his way and knows not how to return. "
"The 'Earthly Ghost' not only mistakenly believes that I am a demon, but he also has many other good people's identities wrong. If this continues, his karmic imprint will become too heavy to purify."
Using his "Deceiver" skill in conjunction with his mind-reading ability, Tyler's charlatan performance had Heloise completely fooled.
