The Dungeon Cupboard is a small room in the Dungeon Corridor. It takes its name from its size and where it is located, in the Dungeons. It comprises an empty room filled with cobwebs, dust and some mice. Here, Rubeus Hagrid hid Aragog. The Acromantula was released by Tom Riddle's Cistem Aperio spell, and he rushed to the forest. This is also where Tom Riddle framed Hagrid, making him appear to be the one who unleashed the Basilisk.
He was sitting in the cupboard, admittedly he was hiding from Wren. Jace knew how attached Wren was to this teddy bear and didn't exactly want Wren to find him with it, because...you know, Jace might have stolen it. It was easy getting in and out of places now that he was head boy so it wasn't hard sneaking into Wren's room to grab the thing. He was sitting on a stool, his wand pointed at it, mumbling every charm he could think of. Jace's skill was in herbology not...charms.
Wren had been moping a little at the loss of his childhood teddy bear; in his defence, though it seemed childish, his mother had made it for him and now, with her dead, it was the only thing he had of her. He'd gone as far as to charm it with the smell of her perfume so she'd always be there and, naturally, with it gone, he was a bit lost. He'd thrown himself into potion making and entered the dungeon to find some more ingredients. Of course, seeing Jace there with his bear that he had more than convinced himself had been stolen, was a shock. He hadn't meant to drop the small vial he was holding, thank god it was empty, but he figured it took away from him having to say anything.
When Jace heard the bottle smash, he jumped, his head almost hitting the roof. When he saw Wren, he panicked and hid the bear in his shirt, as if Wren hadn't already seen it. "Wren," he said with an impish, almost innocent, grin, though it was faltering. "Hi there, didn't think you'd be here."
"This is... the dungeon cupboards close to the mixing rooms," Wren began slowly, head tilting a little as he tried, internally, to make sense of what was going on, "And I make, mostly, illegal potions for the Serpents." He nodded to behind Jace where, in the corner of the room, there was a little box, "That's where most of them are - I didn't think anyone'd be here..."
"Oh," he said after a moment. Jace had forgotten about that side of Wren's life. In fact...he felt rather distant from the Serpents lately, save for Wren of course. "Oh, right. Aren't you ever worried someone will open it? It's an open space..."
"Yeah," he nodded before shrugging, "I put a load of charms on it; most people just see it as a crappy old box and don't bother." His eyes narrowed to the way that Jace's shirt bulged a little, nodding at it, "Are you hiding something?" He had, of course, seen a glimpse of what the other had been holding but had chosen to not jump to any conclusions yet, "Like, is everything okay?"
Wren's eyes narrowed on the bear immediately. He figured, rationally, that Jace must've had a good reason for having it but the sadness he felt when he couldn't find it clouded his judgement a little, "Is there a reason you have him?"
