Both Jack & Pale Rider are fine but injured.
There's a reason why we don't have any confirmation on Jack other than:
However that pans out, I'm inclined to say Jack's safe from a Doylist perspective, just because the lack of POV, not even a simple "huh what do I do now?" or checking in to see how Jack feels about the whole situation is incredibly sus.
I actually don't know if Spooky is alive or not though. I heard he lived but then I heard he died.
