Strays is the fourth Canada mission in Marvel’s Wolverine, and it swaps combat for a scavenger hunt. Logan and Jean Grey land at the Essex Institute in the Yukon with a ship full of rescued mutants, and almost immediately one of them — Leech — bolts and barricades himself in his room. He’ll only open the door for someone who can answer his riddle, which means tracking down his drawings across the facility. The mission also hides both of its collectibles along that same route.
Quick answer: The password for Leech’s door is “A PURR-fect storm”. Find the three hidden drawings first, then pick up the Blood Debt whisky bottle in the laboratory and the material crate in the armory.

Leech’s drawing locations in Strays
Leech says there are four drawings in total, but he hands you the first one himself — a cat, slid under his door as a freebie. The other three are scattered through the institute, and the objective marker only points you to the general area. Hold the tracking sense to paint a blue-green scent trail on the floor and follow it.
| Drawing | Label | Where it is |
|---|---|---|
| Cat | — | Slid under Leech’s door |
| Pirate ship | The Clawed Barnacle | Floor by a statue, past the library and study |
| Wave | Nine lives for the seven seas | Floor of the lounge, on the way back |
| Storm cloud | A+ | Pinned to a wall in the armory |
The route runs from Leech’s corridor down through the main lobby, past Toad on his pillar, into the library and study where Jean comments on the Essex portrait and the Egyptian artifacts on the shelves. From there the trail doubles back through the lounge, then on through the dining room and kitchen to the laboratory and the armory at the end of the hallway.

Clearing the mission also adds the rescued mutants to the Gallery, which the game confirms with an on-screen “New characters are available to view in the Gallery” prompt.
Both Strays collectibles: Blood Debt whisky bottle and material crate
Strays holds two collectibles and no Nightmare Door. Both sit inside the same stretch of hallway you already have to visit during the drawing hunt, so grab them while the “Follow Leech’s scent” objective is active.
| Collectible | Name | Location |
|---|---|---|
| Whisky Bottle 1/1 | Blood Debt | Laboratory, at the back near a hospital bed |
| Material Crate 1/1 | — | Armory at the end of the hallway, beside the door |
The lab is where Walter is running blood samples, and the bottle is on a table toward the rear of the room. Whisky bottles raise your Adaptation Level. Leave the lab, head to the armory at the end of the corridor, and the large chest sitting next to the doorway gives +50 Materials toward suit crafting. The storm cloud drawing is pinned to a wall in that same room, so you can clear both in one pass.
Nothing here is missable. If you walk past either one, you can replay the mission from Chapter Select by interacting with the bed in the Nightmare Cabin, and anything you’ve already picked up carries over.
What happens after Leech’s door opens
The rest of Strays plays out as story. Logan and Jean head back to the lobby, catch up with Callisto and Caliban near the pool table, and watch a Fact Channel breaking news report about a refinery fire in Vancouver at a Bolivar Trask facility. Then it’s back to the laboratory to check on Leech.
Walter shows Leech an ancient device, the kid panics, and his power fires off. Leech’s mutant ability is power negation, and it switches off Logan’s healing factor for as long as it’s active — the first time the game takes that away from you. Walter then explains the device is a fragment of the Helix Engine, built to switch on dormant mutant genes. Touching it drops Logan into a playable hallucination: a dark, blood-soaked corridor full of red-glowing soldiers to cut through.

Logan wakes on the lab table to Essex and Walter arguing over the artifacts. Essex warns him there’s a monster trying to get loose inside him. Logan decides the institute is too crowded, hands Leech his green headphones back as a birthday present, pulls on his brown leather jacket and walks out into the Yukon snow, which closes the mission.
How to confirm Strays is fully cleared
Open the pause menu and check the per-chapter collectible tracker. Strays reads as complete when it shows Material Crates 1/1 and Whisky Bottles 1/1. The same tracker appears in Chapter Select inside the Nightmare Cabin, and your running totals across the whole game can be checked through the trophy progress counters.
If both counters are full and you’ve watched Logan leave the institute, there’s nothing else hiding in this mission — the next stop is Something Much Stronger, which brings back the Nightmare Door and four more material crates.
