Ok so Lobo has just moved in and isn't unpacked yet, right? So then you TT 3 days into the future and then use whomever you'd like as a gossip this person will tell you who's moving. So you chat Peanut up and she tells you who is moving and then if you want them to ping you and give you the date then you just run by them and what-not. If you don't want a date and you'd rather not risk them telling you they've decided to stay just TT 1 day at a time until Isabelle tells you someone is moving.
