(As if on cue, the door opens with the jingle of a bell...and in trot Prince Shining Armor, Princess Cadence, and Queen Chrysalis.)
(Shining is nursing a black eye, as is Chrysalis. Both also walk with a slight limp, looking at the ground like children caught stealing. Cadence, meanwhile, is free of injury and looks annoyed.)
Princess Cadence: [walking up to the counter] "Ahem...hi there, those two--" *points a wing at Shining and Chrysalis, both still skulking* "--got into a bit of a scuffle. I'll need something to clean them up a bit and dull the pain until I can get them to an ER. What do you have?"
Pharmacist: "There you go, bandages for cuts on both of you. For the painkillers, your highness Prince Regent Shining Armour, here's some Phenylbutazone and an Ice-pack for areas of bruises."
Pharmacist: "And as for you in particular, your majesty Queen Chrysalis..." [gives a small glare - he have relatives in Canterlot that was crippled during the Wedding invasion by the Changelings] "... I recommend some highly concentrated Acephate pills."
Queen Chrysalis: "Wait, why didn't you prescribe me the same painkillers as Shining Armor?"
Pharmacist: "Because those drugs are designed specifically for equines, and you're... well, a insectoid-equine hybrid. It'll work less well on you, and you looked slightly more worse for wear then Shining Armor. Trust me, you'll be surprised how well Acephate works to get rid of... 'Royal pains'."
[A moment of silence between the four, as if they all wait for some omnious cue]
Pharmacist: "Anyway! That would be $30 bits in total. Please come back again sometime!"
Queen Chrysalis: "Sence when do pharmacies carry insecticides?"
Princess Cadence: (sounding disappointed) "Wait, you knew what those pills were?"
Queen Chrysalis: (glares) "Sorry to disappoint you, but yes. One doesn't become Queen of the Changelings by skipping chemistry class." [starts to hoof at a bandage over her black eye, but restrains herself] "Dammit, these are itchy..."
Shining Armor: "So what did you do with those pills he gave you, anyway?"
Queen Chrysalis: "I swapped them out for another bottle of *your* painkillers when that would-be poisoner's back was turned as he got our receipts. Then I slipped the Acephate pills into his coffee. Now then, I believe we were headed for the ER for some professional treatment? Fighting is such a dirty business, after all."
