Apollyon motioned his hand upwards after a few seconds of letting the priests maintain their bowing positions. Naturally, Wiper didn't bow; Kami's puppet was beyond even showing the merest semblance of respect and honor unless it was directed to its master. He paid it no mind however.
As the priest known as Johnathan spoke, Apollyon took the time to listen to his voice and examine him, feeling the spiritual energy around him and the other priests. Wiper was included in these observations. Their souls were... crushed to say the least. Subdued and enthralled to serve the will of someone stronger than they. This didn't come as a surprise to Apollyon. He had done such things himself and knew that Kami's little church consisted entirely of puppets. A shame for them really, but Apollyon gave credit to whoever had the will to do such a thing. 
When Johnathan finished his talk, Apollyon nodded, holding a moment of silence as he considered his words and thought of others things. So, Kami had great plans for the city of Fear. Not surprising really. The Crime Mistress of Fear had long held the government within her sway, it was only a matter of time before she tried to completely place herself above it and become the new overlord of Fear.
Great plans. Apollyon looked to the demons and civilians going about their daily duties in the distance, and then to the otherworldly structures and energy wisps curling throughout his Corrupted Sector.
Apollyon smiled. He also had a few great plans of his own, and he felt that they would go along quite nicely wirh Kami's inevitable taking of the government. An opportunity indeed. 

"Representative of Kami," he spoke, "We thank you for giving us this offer. It is one that we'll gladly take Kami up on, and as an added bonus in helping her along..."
Apollyon stood up from his throne and leaped down in front of them. It didn't matter if these priests had skills and powers of their own along with Wiper, Apollyon knew that they'd either be no match for the power of Sheol or against his own. Still, he meant them no harm.
"We'll gladly employ a few certain skills of ours to aid..."
He bowed, his voice sounding sincere as possible. Afterall, as one of the most ruthless lords of Fear, he had to put in a bit more effort in sounding unthreatening and convincing so as to not scare anyone off.
