For all the times you need to talk with someone there is usually at least a couple of options during the week. Whenever you're in this position with anyone just check the map when you arrive at school, after morning lesson, after lunch, before leaving school, in this case look for the twins, go there and see if there's a speech bubble... it's a habit worth getting into anyway because you'll be doing it a lot... If there isn't then you're still missing something. Alice sleepover not sure how far advanced you are... now you have the booze have you gone to the café and spoken to them together (it has to be the day Emily is with them)
