I don't think you're implying that it's not coming back, because it most definitely is.
I can't imagine her part is that substantial, she didn't really have a whole lot to do in the first film either.
I know her show is doing fine, I was laughing at myself for thinking she wouldn't be back.
I wasn't a fan of her character in Thor. I thought Darcy's only purpose in the movie was to provide stupid comedy and eye candy. She is almost like the Jar Jar Binks of the MCU.
I'm glad she will be having a reduced role if she returns.
