Bruce... growls at the suggestion that Zerxus meditate. It would be useful if he could have more detail, it would be a stupidly dangerous act for Zerxus. He ... doesn't want Zerxus to do that. He does want detail. He wants Zerxus to go back to relaxing into his touch.

"I understand your dream just fine."

...He doesn't want Asmodeus to have that additional detail, himself, or Zerxus that open to him.
