Chapter 11; meditation and..hashi?

I plop onto my bed, every muscle aching. I stare at the ceiling and can't help but smile.
The practice wth a wooden katana was fun, especially against Donnie and his staff. I still lose balance a lot, much to my annoyance but it just leads to more practice and origami lessons with sensei.
"Dan!" Master splinter called, and I grunt as I get up. I find him in the dojo, no sight of the boys.
"Today, will be about meditation." I watch as he explains the history behind it and reasons for it to be necessary. Then I sit cross legged on the floor across him and mime his position.
"Straight back-" I straighten myself,"- relaxed muscles-"I sigh in relief, obliging,"- and a quiet mind."
Cue internal groan.
I sigh through my nose before I close my eyes.
There's a moment of silence.
'I wonder where the boys are...it's not my place-'
"Quiet mind, Dan." I purse my lips and take a deep breath.
Silence besides breathing.
Some more silence.
'If my new tattoo is pink I swear-'
"Dan." I sigh and open my eyes, looking to the wall. "You need to get control over your mind." Splinter states, watching me. I chew on my lip.
"How, sir"
I hear a sigh and look to find his warm smile.
"Only practice will answer that question."
I sense another pair of eyes watching me, but my own goes to my hands in my lap. Using peripheral vision, I notice a green body, hints of red. Sensei stands up before me, drawing my attention to him.
"Leo will help with practice in here, Danielle." I scowl at my first name, and stand up. Splinter walks out the dojo, drawing my gaze directly to Raph who's watching, leaning against the frame. I walk up, my gaze on his.
"How was your trip top side?" He frowns.
"We didn't go to the surface." I look at him puzzled. "We went to the hashi.." he looks away.
"What's the hashi?" He glares at me, earning a glare back. "You don't like it, doesn't cancel out my confusion and curiosity. If you don't answer I'm just gonna ask around." I cross my arms and lean against the door frame opposite of him.
"It's a punishment room..we are set in straining positions until we break and tell sensei what he wants. For example-" he steps closer and gets in my face. I bite my cheek and stare into his eyes, ignoring the static growing in my heart." I had to hold a split and knit at the same time, my ankles on rolling cylinders above the ground. Donnie-" He thrusts a thumb over his shoulder, gesturing to the purple clad turtle who's looking a little nauseous."-had to balance on a board that's on a ball in a chair, while bouncing a ping pong ball between two paddles. Leo? He had to hold a sumo squat and balance three eggs. One on his head and the other two held up by chopsticks in his hands." I picture it as he pulls away, breathing out in relief as the panic diminishes.
"For how long?"
"24 hours." I wince and look to Mikey.
"What'd Mikey has to do?" I hear a scoff and look to an angry Raph.
"He held a handstand position on a rotating chair." I nod, chewing on my lip.
"What does hashi mean?"
Raph frowns and stares at me. I stare back.
"What?"
He walks away.
