Joshua blinks at her mention of 'concupiscence' as a potential solution to the Barnabas problem. It...has crossed his mind, yes, but he certainly hasn't spoken of it to anyone, and has never meant for it to be a way to stop Barnabas - just knock him down a peg or two. Teach him that the Phoenix will not be dismissed or cowed so easily.

Her other points are certainly relevant, as well, and he listens attentively. "Indeed," he replies - yes, those points have all occurred to him and/or Dion as they've discussed the issue of Barnabas' presence. "Do you know of anyone with such understanding of this place? Perhaps if we speak with them before Barnabas does, we may yet close off an avenue or two to his plots."

He places his hand over his heart and bows his head slightly, briefly, to Rose. "You have my gratitude, my lady Lalonde. Should a situation arise that might benefit from your sharp insight, I shall not hesitate to call upon you."
