so, a few things are clicking now.
When Dick went into DR, he was wearing the green Ireland shirt. He was wearing that in his DR they showed earlier, and also some on Sunday's show. Now, I know they wear the same shirts repeatedly, but remember how people were saying on Sunday's show in the DRs he seemed more subdued?
I'm guessing that's part of why he was in the DR so long before they told the houseguests what had happened -- they were having to ask him lots of questions and get whatever footage they knew they'd probably need for the episodes. Tha's why he was subdued - he knew he was leaving and if it was for a friend who was sick or whatever, he would have been down about that
