On the day of the Talent Show, Al had gotten his brother moving early to avoid the possibility of Ed running into too many people and wanting to go hide.
After getting his brother settled in at the location set up for him and with a reminder to the individual that showed them how to get there that there were more coming, he went back out to wait for the Ed and Al pair that were also going to be there.
So when they arrive, they'll find Al out on the grounds in easy line of sight, lounging on a bench and trying to ignore the cold creeping in from the stone of said bench.
