While Christine isn't looking forward to smelling the flower that is said to be reminiscent of rotting meat, at least the odor will easily lead them to it. She may be a mage healer, but in her time with the Inquisition, she's slowly been familiarizing herself with herb lore as well. It's good to be well-rounded, especially when a patient requests no magic be used. Therefore, while this mission is about saving the spymaster, it's also a learning experience for Christine. If only these necessary herbs weren't in Ferelden. She's quite all right with the country as a whole, but she's Orlesian and therefore has to pretend she isn't.

"Only in Ferelden would a flower that smells of rotting meat grow." She clicks her tongue and examines the leaves of a nearby bush, because they need three kinds of herbs, and she doesn't want to miss one of the others while waiting for the smell to hit her nose.
