If you listen to Sarita and Sarah talk while decorating the Christmas tree you can here Sarita explain and sing some of the song Good King Wenceslas. This is what she sings
Sire, the night is darker now,
and the wind blows stronger.
Fails my heart, I know not how.
I can go no longer.
Mark my footsteps my good page,
tread thou in them boldly:
Thou shalt find the winter's rage
freeze thy blood less coldly.
I was wondering seeing as how the rest of the season is taking place during winter and the 5th episode slide has snow that maybe Telltale is trying to foreshadow something.
