Hogwarts Adventure

You walk towards the train car that Clementine and Sycamore are sitting in, as you stand outside the car Clementine and Sycamore wave at you and beckon you inside the car. You slide the door open step inside and close it behind you. Clementine and Sycamore are deep in conversation about what house they think they will be in. "I hope I am in Gryffindor like Dad." Says Clementine
"well the odds are about 50/50" states Sycamore, matter of factly.
"Why?" you ask, "there are four houses how can the odds be 50/50?"
"Well you see (*), all the way back to our great, great, great, great, great grandparents everyone in our family has always been a Gryffindor or a Hufflepuff." Explains Sycamore
"Oh I get it," you say
"I just hope we are in the same house Clementine," says Sycamore.
"I'm sure you will be," you say "twins usually end up in the same house." Sycamore frowns at that.
"Yeah I guess you are right" responds Sycamore.
"Well whatever happens we will still be twins," remarked Clementine "anyway (*), you better get changed into your school robes we are getting close to Hogsmeade station." You nod at the two of them and head off to get changed, as you return to the train car in your freshly pressed robes the train starts to slow.
