Why do you think the husband is the one behind Erynn’s predicament? I may have missed some context clues but I’m curious.
I have no plot clues, but a feeling, it seems strange to me that Alexis' father has not yet been seen, and I don't think it's random as what, I think it will play an important role later and I wonder if it is not
intertwined with Erynn.
Then flying with the fantasy about Erynn you can make a thousand guesses, we know she is looking for her father, and what if this is the card that Ethan is using with her? "I help you find your father, you help me in my job by being nice to my clients" Maybe Alexis' father is among them.
