Not yet finished. Also, this is for all three seasons.
Note: If an episode has two ratings shown (TV-Y7/TV-Y7-FV), that means I gave it two separate ratings. The one on the left is the regular rating, and the one on the right excludes strong profanity such as the f-word and c-words.
1. Burning Visions - TV-MA/TV-14-LV - "Fuck" is said three times and "cocksucker" is said once, so it gets a plain TV-MA IMO.
2. Evil Intent - TV-14-LV - Only one use of "fuck", so it doesn't earn a TV-MA.
3. No Rest, No Peace - TV-MA - Just for the scene of Chapel having sex with a stripper.
4. Dominoes - TV-MA-L/TV-14-LV - "Fuck" is said four times, so it gets an L in the uncut version.
5. Souls in the Balance - TV-MA/TV-14-L - The Reverend getting shot in the head isn't enough for a V IMO.
6. Endgame - TV-MA-L/TV-14-LV
