I take the "nothing special of course" as playful teasing, and I like it. I also really enjoy the morning conversation after the graveyard visit. It's a good, serious conversation about power, freedom and the responsibility it brings. (And it makes me pretty sure, that going to the Underdark to babysit all the spawn is something he'd do out of a sense of obligation, not because he is eager to go there.) For me it coincided with Mystra's audience, which made it a perfect conversation for both characters.
