When you first told Pamela you were dating Bruce Wayne, she didn't think much of it. He's a little airheaded, but the man is rich, easy on the eyes, and not too bad of a guy. He hasn't mass-murdered plants and he's treating you right, so she's fine with it.

When you told Pamela you were going to marry the himbo, it became more complicated because, according to you, your husband-to-be is also Batman, the world's greatest detective and her enemy. And to make it even worse, you only told her this yesterday — a day before the wedding. A mere twenty-four hours is not enough time for Pamela to plan the murder of her brother-in-law/nemesis.

So instead, she comes to the wedding and people won't stop looking at her. The surprisingly calm presence of Poison Ivy at a billionaire socialite's wedding tends to turn heads. Pamela sits at an empty seat, watching as you and Bruce say your vows. It takes an agonizingly long time to end, and when it finally does, Pamela is the first to speak to you and Bruce.

"Congratulations," she says, giving you a warm smile and a hug. "I am so tempted to kill Bruce, but I'm refraining from doing it for you. I'm... happy for you. I still think you should just take his money and leave him, but whatever floats your boat."

Pamela lets go of you and gives Bruce a death glare. "And you. You better treat my sibling right, and don't you dare drag them into your little escapades," she threatens. And then turns back to you, friendly again.
