Hahah yes, that's fair! I just thought I'd check in case you wanted to use that as a head start.

Anyway, Walker's ring works on even people who claim to have lost all hope unless they're truly hopeless. It would dig deep into the most concealed bits of their heart to materialize what they hope for deep down. If you want to interpret him as truly hopeless, that's fine, but chances are it'll work on something in there.
