Apollo lifted an eyebrow at the vocabulary that this kid apparently used regularly enough to just throw it out there. Or perhaps the Gryffindor was trying to seem more mature or intelligent in front of an older student. Either way, he found it interesting - and, surprisingly, not in a bad way. "That's fair enough," he conceded. It wasn't as if he would push anything regarding Lily, anyway, so perhaps the other boy was right. Best to leave that alone.
"Ah," Apollo nodded when it was made clear what year his new acquaintance was in. "Third year was definitely a bit odd - mainly because I felt like some of the potions didn't really go together as far as learning went. But I guess it's more about ability level for each age."
He shrugged, but then offered a closed-lipped smile after Stephen's introduction. "Alright, then, Stephen. Why don't you open up the index so we can look through the potions that were covered. I think I recall the shrinking potion being one of them." Apollo's eyebrows pulled together a little in thought, but he went on as he ran a hand through his hair. "I usually try to figure out what the potions, spells, or whatever have in common. Like for a shrinking potion, it makes something small, yes, but it can also make that thing small enough to be inconspicuous. I think third year was also the one with undetectable poisons? Also inconspicuous.
"I mean, if nothing else you'll hopefully remember the names if you can break them up into sections. It always felt less daunting for me if they were in smaller groups."
Apollo leaned forward again, glancing from the book to Stephen. "Do you like Potions?" He asked curiously, almost squinting as he tried to read the Gryffindor's reaction. "Some people don't. It reminds me of cooking, a little. If you make something enough times, you just kinda remember how to do it, even if you maybe need to write down how much of everything goes in. I could help you practice making some of these if you want."
Why was he offering? Apollo nearly frowned at himself but registered his confusion too late for his face to actually pull downwards. Either Christian was rubbing off on him, or Lily's request that he try to be more social had worked its way into his subconscious. Although he figured he might later regret being this nice to a stranger, Stephen didn't seem so bad.
