Yes, i found myself scratching my head and thinking, "are we supposed to know who this Rice guy is?" (Even after they said who he is/was.) and all in front of the big sign for the hotel bar. Oh well, it's probably expensive to film in Hawai'i, they need all the breaks they can get.
I had totally forgotten about Danny's other kid and the bone marrow business; glad they ended up explaining that by the end.
