There is a hall meeting the following afternoon, with pizza and cupcakes to entice everyone to show up, which works on about three-quarters of everyone. Bella shows up more because she's actually potentially interested in having input on the possible hall bonding activities that could be decided on. (The current contenders are apple picking, going swimming in a lake up-province, and making the RAs arrange a scavenger hunt. None of these strongly interest Bella, but someone could come up with something else.)
