In Harry Potter and the Cursed Child play, Albus was originally sorted into Slytherin, but after
Albus and Scorpius disarmed Cedric in past and returned to a new timeline (in which Ron and Hermione never fall in love), they found that Albus was in Gryffindor.
How did Hermione's choice of not dating Victor Krum influence the events such that Albus' personality traits became that of Gryffindor? Maybe, it has to do with Albus not getting Hermione as his Aunt and/or not getting Rose as his cousin and/or getting Padma as his Aunt and/or getting Panju as his cousin. But, how exactly did it change him?
