Had they been face-to-face, her new face shredder would have told him a lot at how well she was taking to this lesson, it also would have had him wanting to slowly de-escalate the situation. But behind closed doors he had no way of knowing what was going on.
Of course he heard the glass break and her scream from the table hitting the door but that was her problem to deal with.
He rolls his head about a little, letting his pupils roll slightly into the sockets to make sure he’d deliver this next bit with a good amount of malice. With a voice that might haunt her for some time, Shadow tells her exactly what’s going to happen.
First, he tsk’s at the door, as if she were a naughty filly in time out. “Now now little pet, if I were to just let you go free once things got a little hard.” A mildly annoyed chuckle comes into Secret’s cell before he proceeds with his next words. “Well, it wouldn’t be much of a lesson now would it?”
Sadistically, he grins at the door and then he chuckles again, this time just reveling a little in his current situation. Normally he’d never do stuff like this, but he’d learned to love breaking in the new students, especially the trusting ones. The fear in her voice makes his insides shrivel up just a little, but it also gives him a rush.
To make sure he hadn’t lost her attention during his pause he gives the table a good smack, wanting her to listen quite close as this was the important part.
In a commanding tone, he snaps off the situation to her like a drill sergeant. Not in volume, but in the condescending tones and hostility of one. “You have one hour, get out to face me and you win. Stay in there and you die like a true maggot.”
After quipping this off, he takes a sizable green candle from his cloak and sets it down on the table. It has a blank card on the bottom for writing notes in and a knife concealed inside the opaque wax. He writes down: “You live to fight another day” on one side. If need be, he’ll write down something very different on the other and cross out the victory message.
“It’s as simple as that.”
"Did you say... lesson? This is supposed to be some kind of lesson? You attacked me and trapped me in a pantry... to teach me a lesson!?" If Secret wasn't so frantic at that moment, she might have remembered that getting trapped in the pantry was technically her own fault.
"That is so-- what kind of-- how could you just-- you-- you're insane...!"
Knowing that this was meant to be some sort of lesson did not make the situation feel any less real-- Secret was still hurt, afraid, and trapped. And to make matters worse, Shadow Protector gave her an ultimatum; get out and face him, or stay in here and... die? Well, at this moment, she was pretty convinced that he might actually carry out that kind of threat. This pony was crazy. Demented, even. And dangerous. And she had invited him into her home.
Secret Tale decided she had more of a chance out there than staying cornered in the pantry, so it was time to figure out how to escape. Kicking the door hadn't worked before, so she didn't bother trying again. She was already so exhausted from everything they had done earlier that she didn't have enough strength left in her for that. But she had another idea; perhaps she could use this small space to her advantage.
She sat down with her back braced against the door, and her rear hooves against the wall across from her. She grabbed a cloth bag and dumped it's contents, then hooked the bag's straps on the door handle above her head. She pulled down on the straps to make sure the door stayed unlatched, and used the wall to push herself backward against the door as hard as she could.
The door gave way slightly; it was working. She pushed again, and again. Almost out, now. She kept pushing. It took a while, but finally, the door opened just enough to fit through. Holding her broken bottle again, she peeked out the door. Even with a weapon, she did not look the slightest bit intimidating. She looked exactly how she felt: scared. Very scared.
Not wanting to risk a confrontation with somepony who was clearly much stronger than she was, Secret chose to do what she thought gave her a slightly better chance of escape: she darted out of the pantry and tried to run for the front door.
