Aang looked up at her and lofted a brow. He didn't realize there were different times. People from the same place from the future. It was a concept beyond him. Momo made a chirping noise and for a second closed his wide eyes at the warm familiar hand. It was almost like the two creatures could feel her anxiety and were trying to cheer her up. Momo's small paws mussed with Katara's hair by patting it down and resting his chin ontop of the "nest" he made,
"...Months? Katara what're you talking about?" There was confusion in his eyes as he looked up at her and watched. "But I'm not even a waterbender yet. How can I be an Earthbender too?" He couldn't wrap his head around the situation-it was to strange.
Aang frowned, he didn't know how to react. So he just gave her a weak smile. "How am I supposed to master water bending now without Master Pakku-wait. Your a master ?" He gave her a cheeky grin. "Then you can teach me! ...right?"
