As most of you know , each season is separated into episodes in the game. Each episode is completed based on certain storyline related (read: Not sidequests!) being finished. Most of the episodes end at pivotal plot points, and the break between them provides a nice spot to save your game and take a break yourself!
At the end of each episode, the credits roll above various images from earlier/later cinemas the player will be seeing, as well as concept art, of characters, and things important to them. (Pretty cliché stuff. :V ) The song usually begins before the credits roll, during the last scene of an episode (usually during poignant dialogue.)
This theme only plays during the episode credits in SEASON 2.

This is an absolutely rad credits tune. Not too sweet, not too hard, varied. Very much 'This is our Story.' ♥
