...basically, she crouches so the Professor can't easily spot her and starts slowly approaching the corner where she saw movement.
"Hello, you little cutie pie," she coos, looking over her shoulder every now and then to make sure she's still out of Professor's Sprout sight.
"Aaaahh!" Sadde cries out, certainly loudly enough for other people to hear.
"Yes Professor," says Miranda, setting down her jar of seeds and carefully helping Sadde get up.
Eventually she settles on "Ow."
"I'm not sure if this is even a useful result, because apparently nobody else is supposed to approach it either," Miranda remarks as they depart the greenhouses for the castle.
"Yeah," she says, looking greener by the second. "Should prolly try to look for friendlier sorts." She makes a mental note to look into plants that tend to not be openly hostile, at some point in the future.
"Maybe ask Sprout. If plants hate you she probably needs to know that anyway."
They reach Madam Pomfrey, who on hearing the words 'venomous tentacula' makes Sadde drink a potion and then casts three spells on her in quick succession, each of which is much improving.
Sadde feels much improved! And, given that she's in the company of someone who might know, asks: "Madam, can I ask a question?"
"Can Transfiguration help with healing? Like, if I break a bone, can I Transfigure it better? Or, say, would a metamorphmagus be able to morph bruises away?"
"Cool! And are there, like, types of injuries for which no specialised charms exist, so that Transfiguration would really be the best choice?"
She nods thoughtfully. "Okay! Thanks!" Then Miranda goes and—" Wait, does that mean I may not go?" she asks.
"Oh. Okay, I guess I can skip learning how musical Singing Mustard is," she says, shrugging. "I just have a date with the Library later today and it'll be very cross if I don't show up."
