Why was Cobel...

Moving the question lower to avoid spoilers. So I'm just going to write some words here so as not so spoil it for anyone who may not have watched the episode yet. Hopefully all of this text helps.

Why was Cobel scared of that man? I can't find any posts about this but please remove if I missed it.

Was that her deceased husband, maybe? Relative? Previous coworker?

Just seems odd that she immediately turned heel once she recognized him.
