Ah, we're sorry that you feel that way. In the context of the story, they
have done stuff together before, which is why they sounded 'familiar' with each other - it was just a very long time ago. In the context of the game, it is still the first time you got to do stuff with her, so I feel that, if you chose to do stuff, it was still a pay-off for something that had been expected since the choice was first discussed a couple of updates ago. Hopefully, the brief mention of it didn't ruin the scene for you and you still enjoyed the work put in with the different variations etc
