Even though Walt noticed his teammates absence, he kept helping the scientists get to safety. he was a little annoyed that his teammates had left without giving much assistance saving lives and stopping the fire. 

"AAAAAAAAAAHHHHHHHH! please don't eat me!" the scientists he was carrying cried in sheer terror.

"Calm down, I'm not going to eat you, I'm trying to help" Walt reassured him and put him down on the ground. after he was done rescuing the scientists, he turned his attention to the fire and was thinking of a way to help put it out enough for the fire department to extinguish it. he flew up the part of the building closest to the flames and landed firmly on the structure. Walt started to flap his wings and created a powerful gust of wind that started to put out the flames. the wind that his wings created was not strong enough to completely put out the flames but it was enough to make it an easier task for the firemen to do it. 

Walt decided that it was time to find his teammates inside the building and he flew up to the opening in the building. he then transformed into a bloodhound and began to sniff around trying to find his teammates' scents. it took only about a minute before he picked up their scent and headed off to find them.
