Peter Lenkov had this to say about Hawaii Five-0's 2011 return, Season 1 Episode 13:

Q: One thing we found out in last week's episode is that McGarrett's mother's death wasn't accidental. Is that going to be play out throughout the season or is it coming to a head soon?


A: When we come back in the new year, the first episode (113) is really going to delve into the Champ box and one of the investigations his father was working on. There's a lot of evidence so one of those mysteries is going to be solved and we're really going to dive into what happened to McGarrett's Mom and answer that question but with that we open up a whole other mystery which will drive us through the second half of the season.
