It wasn't hard at all for Penny to figure out just which cousin and who's wedding. Hadn't Hailey mentioned something about her father getting remarried? It was soon, but then Penny would have had no idea if he had been with the woman for years. It was of little difference to her however, she was wise enough to not ask about Hailey, and not ask about Hailey's little sister in the show. Her subconscious was going to bite her in the arse one of these days.
"Your parents having love triangles," Penny teased lightly, following the other woman into the shop. She was rather excited to see the dress that the woman had chosen. "I can't see my brother in love triangles, he's rather boring in that regard. I always thought he'd marry his sweetheart, but," she said with a shrug of her shoulders. It wasn't her place to speak on the subject, especially since Manny hadn't gone into details about just what had happened between Daani and himself.
