Harry Potter was surprisingly the first to arrive at the Potions classroom. He wasn't even looking for Snape. Standing there, looking around a dash warily (as Snape might stalk through at any moment), he was rather surprised to find the place feeling... a little more like home. He figured that was because they'd been working in teams, lately, and he had studied to get into this class. So, all the bits of esoterica made a bit more sense, recently.
Hermione entered next, looking flustered and a trace manic. Harry watched her, as she laid out not just her potion recipes, but also the defenses and offenses she planned on using to corner Draco Malfoy into admitting that her ideas were better than his. It didn't always work, of course, but it was fun watching them fence back and forth. Still, Blaise had been right, it wasn't a good idea to let them go on the entire class period (and not just because Harry didn't want to spend till curfew brewing).
Blaise entered on the heels of Draco Malfoy, whose aura radiated 'don't talk with me' - a sort of suppressed anger that Harry recognized from his own past. He was pretty sure he'd worn that exact face, more than once, at the Dursley's. When they'd decided to, completely unprecedentedly, get upset about something that they'd wanted him to do the day before. It had been worse than constant punishments, or even being told that what he did was completely wrong.
Before five minutes were up, Blaise wore a concerned frown. "I think there's something wrong with Malfoy." he said, in a lower tone than a whisper, to Potter.
"Yeah, looks like it." Harry said, listening to Hermione fight her way like a machete-wielding superhero cutting through silk. This was most definitely not normal.
"Any ideas?" Blaise said softly.
"How should I know? He's your friend." Harry responded.
"I know... and I'll ask, but I don't think I'll get anywhere..." Blaise suddenly looked inspired, "Although, maybe if You asked..."
"Why d'y' think that'd help?" Harry said, turning bright green eyes on the dark Slytherin boy.
"Eh. He wears masks, you know... we all do, sure, but... Anger's a good way through them." Blaise said.
Harry simply nodded, and a minute later, they all had their potion instructions and they got to work.
