I think you should definitely make sure to let her know you made it to the hospital safely.. and maybe offer to buy her a drink or dinner as thanks for saving your ass. And if it was me, I'd want to hear more about creatures that -until now- I'd believed to be fairy tales - not sure if you'd be as interested, seeing as how you've had a really bad experience - but I'm sure she'd be a great conversationalist; she sounds very wise, aside from being very kind and definitely interesting. Do be sure to share if you ever cross paths with Lilly again!

Edit to correct my poor spelling and grammar.
