I wonder about the candles myself. I doubt he had any. Kelsey was no doubt still exhausted from the night before- didn't she help him at another ranch and also get him something for his stomach because it was bothering him that night, too? (I'll just bet his stomach issue was real- probably knew what he was going to do to her the next day and wanted it to be over.)
She probably was too tired to question his game playing. Also, her Mom even mentioned that Kelsey didn't look like her usual self on the grocery store video- that she usually took care of her appearance but not that day, yet she said when she talked to her that morning, that she seemed fine and in a good mood. No indication that her and PF broke up, even asked her for a recipe.
