What's gotten into you today, she doesn't say. Admitting that she can't tell is offensive to her pride.
But she does think about it.
She thinks of herself as cruel. She's wrong. She tortures people only when it seems to her obviously required by her station and their actions. Or when it takes the form of them stepping into a courtroom placed as her opponent, when she mercilessly takes them for all their worth, inflicting whatever shameful, painful, or ungraceful penalties on them that she can, especially if imposing those benefits herself or her client in any respect. That is simply the cost of challenging her and being shown the error of your ways in so doing.
Irori is not one of her personal choices for additional worship second to Asmodeus, though in some unnoticed-by-her respects she is very like an Irorite. When she does any of that, she prefers Mephistopheles. (Recently, occasionally she spares a word for Dispater and Erecura.) But the notion of pain as a crucible, a tool only to be used to make your servants stronger... does appeal to her.
She never met Sevar in person; she is not competitive enough, on the correct axis, to be in the circles who are invited to the Queen's parties. But what she heard from those who did, she liked.
So she does pause, for a few moments, to wish a fellow wizard, a fellow lady of Cheliax, luck. 'You clearly ascended the mortal ranks on your own strength, and I respect that, and I hope I can emulate it where I haven't already,' she thinks, and 'May your ascent never be stopped.'
