"It's a pleasure, Mantis." Belial has formality from being a diplomat but he's also very relaxed, usually.

"I do, but that is the choice of the individual angel." Nychta and the angel look out onto the rest of the area. "The Celestial and Fallen beings currently residing in the Nexus are more relaxed. We exist here in unity either serving or standing beside our king."

Belial stops there because that could be an intense topic for someone to accept; peace between Heaven and Hell, or at least their angels.
