During Priority: Geth Dreadnought, upon meeting the boarding party again, most squad mates ask Shepard if everything is okay. EDI has unique dialogue, she thanks Shepard for letting them in and that next time she'll try to find a more convenient docking point.
Overall EDI has some interesting dialogue on the ship imo. She's also the only one comfortable on the ship. Must be a synthetics thing 
The dialogue about the geth choosing slavery over destruction by joining the Reapers is very interesting between the squad mates. Unfortunately, to hear all combinations, Tali needs to be dead as she's mandatory for this mission when alive 
When paired with James for example, the dialogue goes like this:
EDI: The geth only allied with Reapers for self-preservation.
James: Doesn't make it right. Synthetic bastards are gonna get us all killed.
EDI: Is it reasonable to expect the geth to sacrifice themselves for organic races that fear and hate them?
At the end of the mission, shortly before meeting up with Legion/Geth VI for the escape, a few geth can be seen running across the walkway where the geth ship crashes down.
