FOX (ended 2015)
I read that he made a comment containing a spoiler and then apologized.
I just want to know if the episode pertaining the spoiler already aired or not.
I haven't made any spoiler and I didn't ask for any, I just asked if the episode containing the one made by Kevin Bacon already aired.
I found out by myself and it was about an episode that already aired (s01e12.The curse).
The spoiler was actually a Jodi Gomes re-tweet done by Bacon in which she wrote:
@kevinbacon is a murderer too! Nice twist @kevwilliamson @thefollowingfox #JoeCarol
The spoiler being that Ryan Hardy killed his father's assassin.
I would call this a partial spoiler.
