Serena was so concerned with Chuck there. That scene redeemed for me how they stupidly wrote the way S acted towards C at Bart's funeral.
I miss their season one dynamic, too. I would like to see Chuck's snarkiness and Serena giving it back to him in a playful way. I mean, he's still Chuck Bass.
It's so sad, I didn't even realized that Serena reached out her hand to him until I was trying to find the POTM, she really wanted him to stay. It's adorable!
