Hi!! not sure about the 2nd ending for bastard, but I can help with Will's last ending!
For Will's 3rd Ending befriend him in the woods the same way you would in his first ending and then sleep at the Inn until the event triggers, it took me a few days of sleeping but thats really all you have to do.
Let me know if you figure out the 2nd bastard ending!
Sure! The exact steps i took are
- on a new save talk to nobody, go straight to The Creek
- Approach Strange Clown (Will)
- Follow Him
- Wade Through the water
- Run Across
- Stay Quiet
- Follow Him
- Try to Reason With Him
- Attempt to Converse
- Ask about Skeletons, Make up, and Bones
- Go back to the Inn and sleep
It can take a few days/weeks of sleeping to get the event, it took a lot longer this time than it did the first time getting the ending so I think its kind of a "random event" you can get after getting Will as a stalker. It took me about 2 1/2 weeks to get the event to pop up this time, hope this helps!
