Answer:
They saved Hermione from the troll.
Explanation:
Hermione had been crying during the Halloween feast in Philosopher's stone. If Harry and Ron hadn't come to warn her and seen the troll, Hermione might not have been able to fight it alone (the troll had moved from the dungeon).
Harry distracted the troll away from Hermione and the troll picked up Harry and started swinging Harry around. Ron then used a spell (Wingardium Leviosa) to knock out the troll with his own club.
Hope this helps!
