Johan looks pleased as Irin accepts the treat. "Good girl, Irin, you're a good pet for your Master. I can practically see your 'tail' wagging." He chuckles lightly, before taking a swig of milk. "Ah, refreshing! I know it's hardly complicated, but you'd be surprised what I've seen maids bungle in my time as lord of Primrose Manor." Then, the biscuit. He looks at the biscuit, examining precisely how it's been baked and buttered. He lifts it to his mouth, slowly, almost reverently, and takes a bite. As the soft, fluffy, buttery sensation fills his mouth, tears form at the corner of his eyes. "Finally. Someone who knows how to bake decent biscuits." Swallowing happily, the prince reaches for his orange juice.
And that's when things go wrong. As he takes a sip, his face immediately screws up, and he's only barely able to turn his head to spit the offending liquid out, narrowly avoiding covering the rest of his breakfast. Coughing, he gasps, "Wh-Who is responsible for this, this poison?! How do you screw up orange juice?!"
As responsibility for each dish is sorted out, Johan calms down, and looks at Kiera coldly. "Your incompetence very nearly ruined my breakfast, but, I'll give you a chance to make it up to me. As I eat the rest of my breakfast, you shall be serving me. Beneath the table. If you can manage to pleasure me with your mouth, I may yet overlook this terrible lapse in judgment. Irin, if she seems hesitant, you have permission to grab her by her hair and force her head down. As for you, Suzu, you've done an excellent job, and as such, you will be attending me until lunchtime. I've had a quick look at my itinerary for the day, and it seems there are no pressing matters, so I plan to do some reading in my study. You will be responsible for ensuring my comfort."
Breakfast results (SECRET BONUS: The Biscuit was worth 2d6 Favor! On the other hand, failing one of the Difficulty 4 dishes costs 2d6 Favor rather than 1d6 because screwing up a trivially easy task makes you look really bad):
Kiera gains 2 Favor for the Milk and 8 for the Biscuit, then loses 11 Favor for the orange juice. However, you now have an opportunity to gain more Favor!
Suzu wins at Breakfast, and gets to accompany the Master during the following segment, unless she wants to beg off, giving up her spot to one of the other maids.
