Billy’s beer bottle
So Mare obviously eyes Billy’s beer bottle when he leaves from eating pizza at the house. She’s obviously thinking DNA test from that. Guess we are to assume she decided against it because it’s never mentioned. She also wouldn’t have though John was going to kill Billy on the fishing excursion.
Loved Mare…but how senseless was she to go offer her condolences to her partner’s mother. Guess only the viewers were privy to how much she bad mouthed Mare to her son every scene we saw her in. Knew that little social call wasn’t turning out well. But she was quite upset about it and felt responsible.
