On "day one" when Harrison leaves Tru's apartment, she points at the toaster as it pops (waffles?). However, Tru doesn't put anything into the toaster and neither does Harrison when he arrives.
Look at the people in the background when Harrison and Jack are talking in the street. It's clear that it's the same extras walking back and forth.
This is the first and possibly only time a 'rewind' starts with Tru already awake.
It appears that there is a continuity error when Carrie is at Davis's house. On the couch when Davis mentions plates that cannot be eaten off of, he places his chin down on his right hand. When the camera changes, his head is up, and at the next camera change his chin is back down.
Jack: Harrison! Look at you, man! You look great! Robust! Like a man who's been taking care of himself.
Harrison: So, my continuing to be alive isn't bothering you?
Jack: Oh. You mean because it runs counter to the plan of the universe and every day you're setting in motion consequences that can only be damaging to the entire human race? Now why would that bother me?
Tru: Don't settle in, Harry. I'm heading out. Something happened and I don't have a clue who it happened to.
Harrison: Wait, I thought your birthday was supposed to be all about giggles and love for the people of the Earth.
Tru: Yeah. I had that birthday yesterday.
Harrison: Whoa. You had a replay on your birthday? Huh. Wait, is there anything I should do, or not do? Uh, did I-did I screw up?
(after day rewinds)
Tru: Not what I wished for.
