Your brother, Wilson, was working on a science machine while you just watched Webber, Wendy, Abigail, Wilba, and Wurt chase eachother. Wendy look expressionless as always, Abigail had her natural expression, Wurt was oblivious as to why they were chasing eachother but was in on it anyway, Webber was running like Sonic The Hedgehog, and Wilba was just bored and decided to join in on the chase.
