Most of this about Liam is correct, however, there is a way to make him realize so much sooner. If Sabrina tells Liam she can't accept the Lily Hairpin, he'll want to know why. Tell him that you are not Olive, and he'll realize what he is doing, so he won't give you the Lily Hairpin.
Later on at the Forest Concert, he'll apologize for what he did before, and gives you the Flower Hairpin then.
