What?? knowing you, I thought you would like Jenny and Alyssa too. maybe even Krystal and Scarlett.
the one that called MC to the power plant the first time is probably shit ninja
I think MC just didn't care enough about Seger to go check what kind of store it is. he only knew women goes there.
Mrs Gilmore can't be Jenny. Jenny is 19-20 years old in the past, so 20 years later, she would be 39-40. but mrs Gilmore is 61. that would mean Jenny would need to travel back in time one time and live in the past for 20 years. but it's not possible because if she traveled back after following MC then she would not have been able to work at the power plant, and tiffany wouldn't say she did up until the accident. also, following MC would mean she would be sent forward in time, not back. and Mrs Gilmore has a daughter, so Jenny would need to be sent back in time to be able to have that daughter.
for now, MC can only travel back 20 years in time, so Lizzie would be 1 year old. unless you meant just a flashback

but the game doesn't seem to do flashbacks, except for MC's dreams with his dad. if there are flashbacks on top of time travel, it might get confusing. especially if the time travel can affect the events in the flashbacks too.
