Ghost Hour at Hogwarts

Why

Ron was not happy with the newcomer. At first he thought the guy was Harry, they looked so much alike except for the eyes, Danny had ice blue ones and didn't wear glasses but besides that? Same height, same wild and jet black hair, same stature. Though during dinner he noticed the differences and in the end he couldn't understand how he could ever think that they were in any way alike, or maybe he just didn't want to accept their similarities.

Danny wasn't as thin as Harry. And Harry had at least a little bit of tan and wasn't exactly as pale as Danny. The kid also was blissfully ignorant when it came to anything magic related. He was excited about every little magical thing, though, in retrospect, Harry wasn't much different when they first met. The blue eyed boy also ate more than Ron's best mate and was actively involved in almost every conversation. He wasn't as held back like Harry but he was very mindful of the people he interacted with. He didn't steal the spotlight and it seemed as though he was pushing his partner into the centre of it, which was kinda like Harry?

He was also sitting straighter, more agitated. It was as if he was as paranoid as Mad-Eye, which was weird. According to him did Danny grow up in a muggle town and had a normal life.
Ron exchanged a meaningful glance with Hermione who seemed surprised at his knowing look. What? He was very perceptive when it came to other people. Especially when he tried. He did grow up with five brothers after all .

Yet Ron couldn't help but think that something was fishy about that boy. He seemed happy enough, maybe a little uncomfortable. He didn't know anyone here after all.
He just hoped that Danny didn't think he could just befriend them only because he was Harry's twin. There was the slim chance that the guy was a Death Eater after all. Maybe a spy. Everyone thought Danny was dead until now, this could all have been planned out. Ron swore he would talk about this later with his siblings and Hermione. When Danny was asleep?

He would probably sleep in the extra bed his mom had conjured yesterday.
Ron swallowed uneasily, he did not want to sleep in the same room as a potential Death Eater! Was his mom mad? Was everyone mad? The way they talked to this kid who looked so much like Harry, the way this Danny prat behaved. It unnerved him, to say the least. He did not trust him and probably wouldn't ever.

In that moment he caught Danny's eyes and the raven haired looked at him confused and then smiled a little. The audacity! Only Harry was allowed to make that face. Ron sighed relieved when his mom declared that they should go to bed. Ron would wait for Danny to fall asleep and then head to the twin's bedroom. If he interpreted the stare they sent him earlier correctly, then that's exactly what they wanted, too.

Soon after turning in for the night he ignored Danny's goodnight wishes and pretended to already be asleep. After about twenty minutes he was sure that the boy was asleep and quietly left to go to Fred and George.

Arriving at their room he noticed Hermione and Ginny already sitting on Fred's bed looking at him expectantly.
"You are late, Ron.", Ginny chided him and Ron had to try really hard to not roll his eyes at his little sister "Yeah, well, I had to make sure Danny was asleep. Sorry that it took so long." Now he did roll his eyes and his elder brothers chuckled while Ron squeezed himself between them.

Hermione leaned forwards and spoke up first "I think we all know what we want to talk about. Harry's supposed twin brother."
"'Supposed'?" asked George with a sly expression and Fred laughed at him "Yeah, how are we supposed to know that Danny really is who he says he is? Remember last school year when we all thought that Mad-Eye was really him? Turns out he wasn't."

George nudged him "Of course I remember that, I was there. So what you are saying is that Danny is not Danny but a spy sent to us by You-Know-who? I had the same thought but if you think about it, it's a little far fetched. I'm sure Dumbledore of all people wouldn't make the same mistake twice. Also, it's almost impossible for a Death Eater to enter this house."
