Okay, maybe it wasn't a good idea that he told the boys that he knew about the forbidden ones too. Well, they are first years, so they don't know exactly where those are located, so he was, technically, still safe and cannot be held accountable for, in case those two children decide to explore it on their own.
He also didn't miss the hint of excitement that came from Oliver. Now, was he turning into a Gryffindor? He hoped not.
"I can show you...but we will not explore it." Or maybe, not show him at all? Hmm...
His father wakes them up at dawn? Ethan wanted to know why a parent would do that. Now that Tom mentioned it, the seventh year realized how lenient his father is. Sure, he wakes up early in the morning, but not that early. Just the right amount of time for him to get ready for the day, and not be late for school.
Now, Ethan approves of the newcomer.
"Of course we will not do anything stupid. Just a good look around the school so you know which is which." That, coming from a former prefect.
"No professor would like to have their students, new or not, coming in late for class you know." Because coming in late meant points deduction.
...
Well, it looked like all of them were ready to explore. With a grin and nod, Ethan got up from his seat, towering over the first years, and gestured them to follow him.
"Let's move out, young warlocks." Ethan headed out for the door and into the
Slytherin Corridor.
