Act 2 is when Vanessa and Jaiden show up. If you already have them, you're already in act 2.If you talk to Claire, she's gonna say Vanessa will come in on Saturday. So you'll need to wait until saturday for the act to start properly.
Thanks, I skipped all the dialogue and I had forgotten that it was on Saturday (I skipped all the dialogue because I had already started act 2 in the other save that I lost)
