These clues range from the obvious — finding the Graduate Badge belonging to an academy graduate right after you meet Catherine — to the rather more vague, with some potentially applying to more than one student. Some characters will have more than one lost item as well.
That’s why we put together this lost items guide, useful for not trying to figure the owner out at all or just for when you’re stumped by an enigmatic description.
Some Tips
Before getting into the list itself, though there are a few important things to keep in mind.
Lost items don’t have deadlines. If you miss giving an item to someone one month, you’ll have the opportunity to the next month during exploration. If you don’t find a lost item one month, it’ll still be there for you to pick up the next month. Students’ locations change each month. Instead of trying to find them by walking around, press R to open the map, and look at the list of people currently in a given area. It’s a much more efficient way to return lost items. Some items in the list are specific to whatever House you chose. Characters might leave the Monastery for a time, but you can hold tight and give them their item when they come back. Returning lost items improves your bond with the other character and, if applicable, maxes out their motivation. It’s a handy way to re-fill motivation without using an Activity Point — and you’ll want to re-fill motivation.
We’ve organized these by month, which is how you’ll likely encounter them during gameplay.
List of Lost Items and Who Owns Them
Garland Moon Lost Items
The first lost item you get is the Wooden Flask. This is actually part of a quest in the game’s early chapters, where Jeralt asks you to find his flask for him. It’s on the Monastery’s second floor, and after you finish the quest, you can start finding other lost items from that point on.
Note there’s no particular order for these either; you don’t have to find one for the other to appear.

Depending on whether you find all the lost items in their respective months — and some of them do take a bit of spotting — there may be some overlap in how you come across these, give or take a month.

There also appear to be some items for a House’s second-in-command (Dedue, Hubert, Hilda) exclusive to their respective paths, though since we haven’t played through all three paths yet, we can’t confirm this for sure right now.
Meanwhile, be sure to check out our other Fire Emblem: Three Houses guides for help making the most of your time at the Monastery.
