Forum:Shortened dialogue with Liara, bad consequences?

Hello. I have a character who had a relationship with Liara in ME1. Now I've finished all the Liara quests, and I've played a lot after that. But today I've discovered on the wikia that, when last talking to Liara, I missed some speech lines. Guess I just didn't notice them... I've missed the lines where Shepard asks Liara the reason for her hate towards the Shadow Broker, and Liara explains that he tried to steal Shepard's body. Then there's the point where you can choose to lighten her up or tell her she did wrong. Now, I lost all of that, I went back and made some experiments with the saves and those lines don't seem to be changing anything, but I'm not sure. Will this impact maybe ME3? Should I go back and replay from that point (I'd hate that...)?
