I'm not a big Sonny and Brenda fan, but I loved the scene between them! It was handled just perfectly --- very poignant --- just enough, but not too much. A little bit of reminiscing, a little bit of catching up, and the hint of deep feelings. And it was perfect that Brenda honored her engagement and didn't start smooching with Sonny, and perfect that he really valued what she had to say and left to go back to Port Charles.
P.S. Doesn't Vanessa Marcil have the greatest laugh! She's so spontaneous! I've seen her on a couple of talk shows recently and she's exactly like that --- she seems to be very upbeat -- a lot of fun and genuinely tickled by life. I hope the powers-that-be allow her to bring some of that to her characterization of Brenda.
