Broken- Slade and Robin

The lesson

Robin's POV
I sighed irritably, staring up at the metallic ceiling, I was filled with anguish and despair but I refused to let Slade see that...
My entire body was aching from Slade's strict training regimen, he's very dedicated when it comes to training, I would admire him for it if he wasn't a psychotic kidnapper.
Suddenly, his spine-chilling voice crackled through the intercom- "Apprentince... Come here boy." He demanded.
I shakily responded, "Yes, right away..." a silence lingered as I headed towards the door-
"Right away... WHAT?" He hissed.
I bowed my head before grunting through gritted teeth
"Right away... Master " It causes me great trouble to force those words out of my throat.

I eventually reach Slade's doors, I hesitantly reached for the handle and pushed it open carefully, "You... ordered my presence, si-master?" I asked cautiously,  my voice wavering slightly as I neared the end of my sentence. He simply looked at me fiercely, his single eye boaring into me.
"Apprentice... Would you care to explain THIS?!" He snapped, holding between his fingers a switch blade... My switch blade! I had been using it to chip away at the weakly insulated walls of my 'room' . An audible gulp escaped my throat and I felt beads of sweat begin to sliver down my face.
" Master... I-I um... You see... it's just..." I spluttered desperately,  I needed to think of a valid excuse! I couldn't take it... I knew what he'd do to me!
Watching me at a loss for words brought him pleasure... I could tell that beneath his mask, he was grinning at my poor attempts at justifying myself.
"I asked you a question... would you care to explain it? Or should I explain it to you? ..." barked slade,  his fists clenched in rage.
I couldn't summon any words, I just looked down at the floor towards my steel toe-capped boots...
"Because... What this looks like to me is another one of your brainless attempts at escaping me..." Slade droned on but he was right... I left the switch blade in plain sight and now I was certain that I was going to regret it...

Slade suddenly stood up and drove his fist into my stomach, earning a small whimper... He had hit me with so much force that I had fallen to my knees heaving and trying desperately to regain my oxygen. Slade took no notice and practically slammed his metallic foot across my face, an audible crack was heard and I grunted unintelligible words, realising that he had broken my jaw. I clutched my cheek and struggled to my feet, my face stretching into a frown.
" When will you learn, boy? I have provided you with everything you could possibly need, and yet this is how you repay me..." continued Slade, gripping the front of my uniform and glaring into my masked eyes.
" Everything I could possibly need? ... N- No... Nobody needs to be tortured you piece of-" I was cut off by Slade grabbing my wrist and twisting it mercilessly.
"AhhhhhhhhhhHHHHH! ..." I screamed until my voice was hoarse, finally Slade left me on the floor in a struggling heap, wheezing and grunting. I sighed in relief as I heard his footsteps receding and began trying to pull myself up to my feet.
Suddenly my heart dropped... He was coming back! I could see him in the corner of my eye! He was holding a whip! I began trembling and desperately trying to scramble away.
"Please! Pl... please! Don't hurt me, master! I-I  I've swear I won't do it again! Just please please don't!" I begged helplessly on the verge of tears.
" Don't be so pathetic, apprentice... this won't take long " whispered Slade,  forcefully pushing me down onto all fours. He grabbed the neck of my shirt with a vice-like grip and wrenched it from my torso, throwing it in a clump across the room.
He ran his fingers along the edge of the whip, letting out a dry purring noise.
Suddenly he raised the whip above his head and slashed it against my bare back.
A scream erupted out of my lungs,  as I arched my back in the pure excruciation, I began panting and whimpering out of fear...
He struck me again and again, it was relentless.
30 lashes!

40!

50!

I had lost count, my vision clouded up with dark spots and I began to slip into unconsciousness...
