Well..... I did start the seed in the house but there's something strange. The Elms calls that I was supposed to get is ((E skipped) K,E,E,P,E,E,K,E,K,E). But when I started the seed in the house, Elm calls that I got appeared as E,P,E,E,K,E,K,E,K,P
I mean if you look at the patterns, 3 of the first calls have been taken when I started the seed. ((E,K,E) E,P,E,E,K,E,K,E,K,P)
EDIT: And, yes, I did defeat the elite four.
