Riva poured the contents of a vial into a steaming pot of tea. She'd chosen a some cinnamon herbs for this particular pot; cinnamon burned a bit on the way down and she had a feeling her steely husband would enjoy it. Riva took a long, deep sniff of the pleasant-smelling fumes before placing the lid on it and pouring more of her potion into the cream.
The plan was in motion.
The odorless, tasteless serum was an old recipe, one she made large batches of quite often. Its effect loosened the tongue by making the consumer more inclined to speak their thoughts aloud. Rather like alcohol, only it didn't cloud your judgement; people were still loathe to discuss things they knew to be out of character. She usually injected it straight into the vein in its most condensed version, almost taking away a patient's haven of thoughts entirely by forcing them to speak everything that came to mind. (as one might imagine, she'd heard some... interesting things from people under the serum's influence) But Caden couldn't know about the potion, or he'd... Well, she didn't know what he'd do and that was precisely what frightened her.
When she ran into a maid, she called the nervous thing over. "Excuse me, I'm looking for Caden. Do you know where he is?"
"Uh..." The woman couldn't meet Riva's eyes and trembled slightly. "He just got back, Your Raven-ness. He's in his study."
"Why thank you. Could you direct me there?"
The maid nodded and did so. When Riva got to the study, she didn't bother to knock, but let herself in with the tray of teacups. "Well, well, well, good evening, Caden."
