Does 'we need to talk' mean in person? That's a tough one because she already has given this a lot of thought as you walk in unprepared. If you're curious, call her back and ask what it's all about. Sounds to me like some sort of closure thing or she's just checked back into reality and realized what happened. Either way, it's your choice to give her the time or not. I personally would not meet her in person without some indicator of what this is all about, then decide if it's something you want to put yourself through.
