Your comment is reassuring in a way. Luke indeed is the kind of guy who hides his issues under many layers of vices, and that's something we intend on addressing on his chapters (they are optional; you can pick which guests you hang out with, you'll see this content if you choose to.)
I can say Luke is a character for whom we have some fun ideas. As you put it, "maybe get him drunk and have a candid conversation or something like that" is definitely something we can do!
Thank you for your feedback.
