Raph
To say that we're surprised that a random person just collapsed through the portal would be an understatement. Escpecially with the state they're in.

He has wavy black hair, a few silver streaks in it, which just reaches his shoulders, framing his angular features. He has the same skin tone as Rarity but his is heavily bruised and cut, especially across his arms. He's super slender- heck I wouldn't be surprised if a Pinkie Hug snapped him in half. He's wearing black jeans and a tattered black tshirt, a satchel slung over his shoulder. His shoes are black with silver laces and, despite being unconscious, is shivering. I'm guessing that the portal, despite knowing former ponies will need clothes, it doesn't know how to be weather appropriate. What's worrying about the situation is the amount of blood spilling out the injuries.

"We should get him to hospital," SciTwi... or just Twilight really... suggests.
"We can't," Sunset objects. "Think about it, how are we going to explain this plus his files?He won't have any." Damn. She's right. Still that does raise an issue on what to do.
"At leadt I've been doing a medical degree the last few years on the side," Twilight says. "That'll come in handy."
"I also picked up some stuff- I could hardly walk into a hospital," I add, matter of factly.

Well it's true. If a mutant turtle walked into a hospital back where I came from anyone would freak out.

Sunny goes to the portal and touches it, as if it'll somehow give answers. Then her face pales.
"What's wrong?" I ask, concerned.
"The portal. It's gone!" Sunset states, panic evident in her tone. What?? How??? Well this is going juuust great.

Rarity goes to get the car so we don't have to go home with an unconscious guy. That would get us a lot of weird looks and possibly getting arrested.

We lift the unconcious person into it and drive to mine and Sunset's appartment.

He's been unconcious around eight hours-thankfully though the injuries aren't as bad as they looked. Twilight wrapped them in bandages and said, with enough rest, he'll be fine. I still wanna know what the shell happened to him...whoever he is.

He starts to stir and a pair of purple eyes with silver flecks flutter open, blinking against the light. Immediately an avalanche of questions are sent his way.
"Who are you?!"
"Where's the portal!?"
"Do you like parties?!"
"How did you know about the portal?!"

The questions all overlap so the poor guy just gives them a blank look.
"Uh...can you say that again slowly?"he asks, breaking into a cough after. Sunny passes him a water, which is when he freezes, noticing his apperance. Shit. This is going to be interesting.

"What has happened to me?.."
