When watching fireworks I noticed what I think is a change in dialogue
(i used the name "Terlor" as an example, it's whatever your character's name is)
what shauna says If your character is female:
"um..." "you know....." "i really hope we get to be great friends, Terlor" "we haven't even seen them yet, but I know i'll never forget these fireworks" " 'cause I watched them with you, Terlor" -'the fireworks go off' "..." "wow!" "That. Was. AMAZING!" "i never ever want to forget this, so ill keep this memory in an album in my heart!"
what shauna says If your character is male:
"um..." "you know....." "I've never watched fireworks alone with a boy before" "we haven't even seen them yet, but I know i'll never forget these fireworks" " 'cause I watched them with you, Terlor" -'the fireworks go off' "..." "wow!" "That. Was. AMAZING!" "i never ever want to forget this, so ill keep this memory in an album in my heart!"
Yes there is.
If the player is Serena, Shauna will say: >Um... You know... I really hope we get to be great friends, (insert player name)...
If the player is Calem, Shauna will say: >Um… You know… I've never watched fireworks alone with a boy before.
Shauna, Bulbapedia
Instead of "Uhm... You know i've never seen fireworks with a boy before" it will say "Uhm, you know I hope we get to be great friends, (your name) Hope I helped!
