...and brought her up to the second floor.

Forrest was very careful to keep clear of the suits of armour, though. He even eyed them suspiciously from afar, and soon enough, he was explaining why.

"Keep away from those, they're malicious," he said. He'd already let go of her hand and leant forward towards her ear as they faced them. One hand pointed at the armours. "They attacked me last year while I was doing astronomy homework." He was 200% serious, and his voice betrayed his fear. He had never been avenged... but she was the person he would like to keep out of trouble, so he didn't say that.

Instead, he turned her slowly by holding her from the shoulder. "And here we have arithmancy classroom, headmistress' office--protected by a password--and girls' bathroom." His hand was pointing at places as he named them. He couldn't warn her about Mrytle, though, as he'd never ever wandered even somewhere close to the bathroom. So she'd have to see it herself.

He was curious just how much she would remember in the end, seeing as it'd taken him half a year to get everything correct.
