I have both logan discourage and courage longan.
Well first off your gonna need need to have bernards searches for his friend done, and logan unlocked (Kinda obvious as you can't really get to the event without them) then when that's done and you've got your logan choice and have either corrupted or normal you continue on and need to have the rumours of the beast and first search done with Logan. (Rumours of the beast is one where you talk to everybody excluding hayden) and your also gonna need to have defeated scar or seduced/spammed lust potions/submitted to him for access to the secondary forest area where you find aconitum which is required for wolfs bane, and you gotta read up on the plant to find out its useful, you also need to wolf's bane. Then after you have the rumours and first search done after 21 until midnight you can have the event begin where you have to choose between one of them and let the other turn. But that's not the end yet, you when you go home after the event get a thought bubble saying the witch might know something (it has to pop up or her quest won't appear) and it's also only during night time. And doing that unlocks the wolves den which depending on when you go has different enemies, such as day yields wolves and the alpha wolf boss which you need to defeat to finish the witchs quest. Then wait a couple days and werewolf L/B will appear by chance at night.
