The final straw for me was when Dax Facetimed Gemma on her Samsung phone, but there were so many inconsistencies throughout this I was going insane. Which is a shame because it's such a cute premise.

Dax thought she was a stalker who broke into his store and knows intimate details about him (including where his sister works) in the beginning but then NONE of her behavior is suspicious to him after he thinks she’s cute, even though she just shows up at the bar he frequents and really wants to join his super random curling team?

Once we get past that, Dax knows NOTHING about her in this timeline except she’s reluctant to date him, keeps putting a halt on the flirting, but instead of reading the signs he won’t stop until she talks to another dude and he's salty about it?
He says he and Sunny only talk at curling and aren’t close then why do they have a secret handshake and why was HE the one giving her a ride home and why is HE the one she’s texting that she got to work safely?
Why would the super random friends/strangers of Gemma's invite Dax to their wedding?!?! They have never met him and for all intents and purposes this is their first date and they aren’t even that close to Gemma so it's weird enough they're inviting her when they just saw her randomly out one night.

I don’t understand why Elliot looked familiar / looked like Stuart. That was never explained im very confused.
Sex positive does not mean you talk about your hookup the night before in front of your six year old.
Kiersten went from “Trent is my best friend” to that man bought me a mop as an anniversary present in literally one chapter. Zero consistency.
She doesn’t put a lot of weight into the act of sex, but had a sex DREAM about him once and tensions were weird for weeks? And couldn't hook up with AU Dax because it might be weird with OU Dax? Make it make sense.
But literally, when her having a Samsung phone was a key point in her realizing she was in an alternate universe, you think they would remember he can't Facetime her.
