Dusk
It's dark, the air thick, making it hard too breathe. It's too hot. I can't move. My 'wrists' (I think that's what Sunset called them) are bound behind me, the familiar feeling of a blade travelling near my throat, held by some unseeable figure. The other hand is tightly gripping my hair, meaning if I move my head, at all, I'm dead.
"Did you really think you could get away?" a voice mocks, the grip tightening. My blood runs cold - I know that voice. A laugh fills the room, the blade travelling down so it's just on my... 'shoulder', formally the start of a leg.
"How long until you break again, Dusk?" they muse. Death would be better than this...

Something cold hits me and my eyes shoot open.

"What..? I was actually sleeping  for a cha- I'm still here?" I begin, then realise I said that out loud. They hardly need to deal with my problems.  "I thought the different dimension stuff was a dream.." I say, hoping to divert from my previous thoughts.
"Is there anyway Sombra could have got through?" she asks. That is not something I want to think of.
"I don't know..maybe," I say. "It's hard to tell without magic. But...well...he's powerful and if he got through....maybe." 

"Maybe?!" she snaps. Ouch. Temper.
"Sunset. Maybe you should calm down," Twilight suggests.
"Sorry," she mutters. "It must be bad enough being stuck here." Yep...

I remember what Twilight told me.
"If he did get through though..." I say"Then you lot should have powers..." Sunset's hands, after a few moments, start to glow. So he did get through... great. Just. Great.

"OK, so what do we do?" Twilight asks.
"...Why are you looking at me...?" I ask.
"Twilight said in the letter that you know Sombra," Sunset says. Oh..."So you can help. "

Me. Help. Right...all I can do is be a hinderance, not helpful. I couldn't even stop Sombra from getting through the portal let alone stop him from doing anything else. I'm useless in this situation.
"I don't know," I reply. "Find a way to get Discord over here so he can beat Sombra? ...Find a way to reopen the portal...." That could work...

The group agree then head off to make food- only Fluttershy remains.
"What did she mean by 'you know Sombra'?" she asks me. I just shake my head.
"It's..." I begin then stop. It's not nothing. "It's something I don't like talking about."

That's more honest.

I chew my lip at a thought- with Sombra here reality may also become a nightmare.
