As regards Adriana's arm... it was previously stated in another thread that she was having trouble with tendinitis.
The bandage on her arm looks to me, and I'm not a doctor, like a post-surgical wrapping. I have seen similar style bandages on a couple of friends who have had wrist surgery. And they had to keep the wrist elevated as I've seen her do.
So, I don't believe she broke her arm as Chip2020 has commented.
Also, I think it is possible that she was held in a surgical center overnight after some surgery... and very likely that Daniel took the opportunity to get fall-down, puke-all-over drunk.
And, to comment on the comment of dfCcap... I believe that they have one of the more stable relationships on RLC and that neither has "stepped out on the other".
Just my opinion folks.
