Hana glanced at Cade after questioning him, not like in a mean or like a rude way, she hopes the boy won't think of the wrong way. That question is just completely harmless, but maybe out of Hana's sharp tongued mouth, it sounded rude. Hana simply shocked that the boy, the Ravenclaw boy, has no plan and idea of what he's doing, and worse, both of them don't even know if something exist behind the wall. What if that thing is behind like an armour, or embedded in the floor. Why must it be the stone bricks on the wall?
As Hana listens to Cade's response, she kind of understand what he's talking about.
" I mean, that's true. Discovering, find the unknown, things like that always start with a mystery. But, are you really sure, like 100% sure that that might be at least something for us to discover, like those myths, before we realise we're wasting our whole time at the very end? Not that I mind that." Hana said, nodding with understanding. Hana loves hunts and discovery, she really does. For example, when she was young, she loves those easter egg hunts and treasure hunts. But during those times, she knew she was hunting for at least something, well, not like this one, where she has no idea whether there is the 'something' to find, whether this is probably just a poor plain wall, who got suspected to be hiding a secret by two students. And she knew, maybe to the eyes of other people, she's just like an idiot, knocking on random normal bricks like she hasn't seen them before in her whole damn life.
But you know, Hana never gives up. *coughs* That's fake. *coughs*. At least she doesn't when she's helping someone else. So, there she is again. Investigating that wall, knocking those bricks. She just hopes the wall is not innocent, so she won't feel guilty for knocking and hitting it.
...
Hana stared at Cade as he examined Hana's diagram.
Hope it's right, hope it's not just some usual stone sound. When Cade told Hana that she might have found it, Hana's eyes widen slightly, and of course, she's smug about that.
"So, what's behind this brick, do you think we should like break it or what-"
Hana slowly turned around to see where that mysterious voice is from. She's not scared, just annoyed, like an interruption. She hates interruption, she would've punch that person for eavesdropping, but she won't cuz she needs to maintain her composure. And yes, she hates eavesdropping much more, though sometimes she does it herself, for academic purposes, of course. And she saw it, ghost, Bloody Baron, to be precise, and her face dropped. Not of fear, but the fact she can't even punch that. That's her first time seeing him, it's fascinating, to be honest, but still, she hates him for eavesdropping.
"Wow, fancy blood there" Hana mumbled unintelligibly and sarcastically while rolling her eyes.
She locked eyes with Bloody Baron, who seems surprised to see Gryffindors here. She answered,
"Yes, a Gryffindor, who don't want to go to a ball, obviously. And why are you here Baron, why not join those fun with your other friends and your precious Slytherins. Remember to tell my brother I don't miss him." Pausing for a second, she continued.
"And yes, we are investigating this wall. And I don't see a big problem about it."
Hana glanced at Cade, searching for his expression when Baron said it's just pipes.
"Just pipes? Then why does this particular brick sounds different? That's somehow in the centre of the other normal bricks?"
