Was he talking about Karina?

Brian narrowed his eyes and asked, "You mean Karina, right?"

“Of course not. Are you unaware that I've been wooing Rosalynn for a while now?"

Barlow turned his attention back to Rosalynn and added, "I agreed Karina to seduce Annalise so that Karina would put in a good word for me with Rosalynn. I was planning to tell Rosalynn, but I suppose it's just as well that she was here to see everything unfold. Well, Rosalynn? Were you impressed?"

He was obviously teasing her.
