"My excuses never seem to pan out, do they? Tree's and elephants. Fun to say though." Albus didn't mind the bruises, he didn't mind the full body aches that he felt after a lesson with Bella. Actually, he rather like the aches, they testified to a good work out and that he could take as well as he could give. Which according to Bella, was better and better each week.
Really, Albus wanted to tell Scorpius. Who else would he want to tell besides his best mate? Even if he and Bella were related, and after the things they had done the other day, it did matter. Scorpius couldn't tell, couldn't ask where she was, because only he knew and Albus wasn't going to let the people on the Island go and hunt her. Didn't change the fact that he wanted to tell, wanted to brag about how good he was getting and what he was learning.
