This is Lisa's daughter, Suzy. She's been sort of like a sister to you for a few years now. Your relationship with her is not very good though, as she felt abandoned after you left for college and has developed some resentfulness towards you.
Maybe that relationship can be repaired though, because you remember her as being sarcastic and funny and even sweet sometimes, even though she doesn't like to show it. You've started developing some fuzzy feelings towards her too, which feels weird, because she was 16 the last time you saw her - just a kid. But now she's 18, driving, has a job down at the Java Lava and even has a boyfriend. Still, those feelings are strange and you shouldn't be having them.
