'Nancy Drew' Episode 5 teases new character linked to Tiffany's murder as Laura is sure the Hudsons are involved

Major spoilers for Episode 5 'The Case of the Wayward Spirit' of Season 1 of 'Nancy Drew'
Last week in 'The Haunted Ring', a new character comes to town in Horse/shoe Bay.
Tiffany Hudson's (Sinead Curry) sister Laura Tandy (Stevie Lynn Jones) is back in town to find out who killed her sister. Utterly unconvinced with the results of the autopsy, which reports that Tiffany died of natural causes, Laura points out that no 28-year-old healthy woman just drops dead out of the blue. Laura is sure her sister was killed and that the Hudsons were somehow involved - if not the entire Hudson clan, she definitely doubts Tiffany's husband Ryan Hudson (Riley Smith).
With her search for the murderer ongoing, in the last episode, she breaks into Nick's (Tunji Kasim) room and steals a pen drive that was hidden in a compartment in the box Tiffany left him. While this is still being shelved out, the show added another new character to the mix.
Miles Gaston Villanueva plays the role of Owen Marvin, a real estate mogul and Ryan's rival on the show. His character was earlier reported as: "Sparks fly when Owen meets Nancy (Kennedy McMann), but she soon learns he may not have an alibi for the night Tiffany Hudson was killed."
And that is what happens. After Owen approaches the Drew Crew at the Claw to cater the gala he is hosting, there is some obvious tension between the two. But in all possibility, this attraction or 'sparks' are one-sided - Owen's side.
Either way, this palpable tension leads to them working together on one plan. At the end of episode 5, Nancy seeks Owen's help to dig up something from the grounds of her high school solely because being in construction and real estate, he would have access to the tools that would help her dig underground. But their growing correspondence is increasingly upsetting Nick, making him insecure.
Just before this, Nick and Ace (Alex Saxon) make the discovery that Owen might be, in some way, linked to Tiffany Hudson.
The pen drive that Laura stole from Nick's room contains a link to a password-protected site. She tells Nick and Ace that Tiffany was gathering evidence against the Hudsons and that is perhaps why she was harmed. The issue is that Laura doesn't know the password and is one attempt short of being locked out.
After George's Chinese exorcism, Nick finds out the password is 'Dantes.' When Ace and he open the link, there are several insurance papers that are, interestingly, singed by Owen Marvin.
What is the connection? Since reports had mentioned that he might now have an alibi for the night Tiffany was killed, could it be possible that he is the killer?
'Nancy Drew' airs on Wednesdays at 9 PM ET/PT on The CW.
