S1E01 - Pilot

NINA SHARP to Olivia in 'Pilot': "I would say this to my own daughter..."
This is a foreshadowing of the timeline in which Nina raised Olivia and Rachel as her own children.
NINA to Olivia in 'Subject 9': "So you told me about the Fringe Event, but I think you left something out. It's happening to you, isn't it? Now, come on. I haven't seen this much fear in your face since Bobby Hastings asked you to the prom. So what can I do to help you, dear?"

S3E10 - The Firefly

In 'The Firefly' Walter learned that his favorite band, Violet Sedan Chair, broke up after just one album because of an unlikely chain reaction of events started by Peter in 1985. In 'Subject 9', which takes place in the timeline where Peter was never raised in the Blueverse, Walter has a poster for a Violet Sedan Chair project that never happened in the original timeline.
