When mapping out this season a long time ago, the plan was always to deal with Mara for a time, then eventually split Audrey and Mara, a big twist in this season’s Mara storyline. Not the only twist, however…
The writers knew in advance that they wouldn’t have Adam Copeland (Dwight) for two episodes this season, and luckily it worked better for this episode for Dwight not to be in Haven. He’s in all the remaining episodes — quite a bit…
"We really wanted to see this scene — the first happy, peaceful scene together for Audrey and Nathan as a couple since the opening of episode 10 of last season. We felt they’d earned it after so much trouble (pun intended)." - Brian Millikin
The writers very much wanted this episode to reflect what life in Haven would really be like for Audrey and Nathan in the wake of Mara’s rampage all season. It’s a complication the writing team never got to play last season when Audrey pretended to be Lexie for a time.
Reggie was named after a character in the HBO series “True Detective,” a favorite of the Haven writers. That’s where his backwater drawl initially came from, too, as that show’s first season was set in Louisiana.
Rebecca is played by Kirsty Hinchcliffe, Lucas Bryant’s real life wife. Haven's writers thought it’d be fun to have them in this scene together — as Nathan figures out just what kind of situation he’s in here as a ghost.
The concept for this episode is one the writing team considered using for several seasons — the nickname was always “Ghost Nathan.” "We felt we’d been a little light on the amount of Nathan ever since Episode 3 of this season, and wanted to have heavy Nathan episodes for 7 and 8." - Brian Millikin
Haven's team wanted the Trouble for this episode to help them tell a story about Mara being immune when Audrey isn’t anymore. The mid-episode twist that Mara alone can see and hear Nathan was how this episode was first pitched, and never changed throughout the whole process.
"We writers felt the best effect in this episode wouldn’t be CGI — it would be the other actors ignoring Lucas Bryant in scenes with him as a ghost, and it’s not as easy a trick as anyone though it’d be." - Brian Millikin
If the layout of this Guard warehouse looks familiar, it should. It’s actually the same warehouse the Haven staff used as the interior of the Barn, in Episodes 13 of Season 3 and the premiere of Season 4. The team had to cover the walls, which Haven's art department painted white two years ago.
