i am glad i was able to help you . idk if you also play repeat but in case its the same as with TB there also is a Audio folder with all the music files . haha yeah i hope the both become more . i also think we will see a turn in the relationship of Cole and Calder later.
wish you fun to listen to all the beautiful music
Spoiler i guess:
i think Calders grandpa also is Coles in the end of Capter 3 you see a family portrait with i am preety sure about it ( but its only waht i guess) Gaius in the back Calders Mom in the front another Hyena on the left (you look at the portrait) and another person/Hyena who i think it could be Marrow . as we know Marrows sister died and also Calders mom .Marrow named his Axe ( translation: sisters voice ) Calder tells a bit about his uncle and Gaius seems to have an interest into Cole as the meet in the Tavern. and it would fix the Rumor of Marrow once was a nobel/member of a nobel Fam and leaves his home since Gaius /his Father seems to be/was an asshole and it would also explain why Marrow dont realy like magic , so i bet my ass on it . Calder is Coles Cousin
