While Russell is busy being the worst murderer of all time, Detective Frank realises that Russell isn't who he says he is. (Surprise!) So, um, who the hell is this stranger?
By now, after seeing her husband casually destroy their garden to bury a body, Jennifer is suspicious. She proceeds to limp out of their bedroom to try to look through his computer files, but she needs a password. What does she try to type in? Variations of her own name! It's bizarrely self-centreed and hilarious.
Russell interrupts her sleuthing by coming home with a brand-new phone for her that . . . doesn't work. He blames it on their remote location, but come on, Jennifer!
Detective Frank pulls the hospital surveillance footage and realises that Russell just *casually* showed up to the hospital right after the accident. He then somehow matches one of Jennifer's tattoos to her maiden name — Allen — and it's game on. He shows up to her parents' home only to find a sh*tload of letters in the mailbox and a horrific smell inside. You guessed it: both her parents are dead and have been for a LONG time. Woof.
Cut to Russell going out to do errands and locking Jennifer in the bedroom for no reason whatsoever (uh, major red flag!). Jennifer happens to find her real ID in Russell's wallet, confirming her worst fears, and proceeds to break out of the room using a bobby pin in all of five seconds. (I've tried it; it's NOT that easy.) She then successfully guesses his password (which is a variation of her name, joke's on me) and finds pictures of her and her real husband that Russell obviously Photoshopped over.
We learn that the man who's holding Jennifer hostage is her ex-coworker Ryan Garrity, who apparently has had a crush on her for years. Once Jennifer started dating and married her actual husband (also a coworker), Ryan snapped like a toothpick. So, where's her hubby?
