I get that they can’t post certain things because they don’t want to give away too much as to what his character will do etc. But it wasn’t a big deal back then to post a picture of the two of them together, or even a little tweet saying they’re shooting together or whatever. I get that Matthew doesn’t tweet, I really didn’t expect him to because he’s been sort of off twitter again for the past month. But CC seemed so excited about it and always answered questions about him and him being on the show beforehand. I just have a feeling that this time, they really wanted to keep this secret and idk why.
I was also thinking that maybe they do have a few pics (or like the CT social media team has) and they might just post/publish them closer to the air date for promotion.
