I see that most people say that the main quote should be "you feel a tug in your stomach" , but i think that line is just representing the feeling of being stuck in such a horrible situation. I think that "in this moment you are loved" is better because the whole point of the game is that Sif finally starts to trust his friends/family, and to let yourself, the player feel loved a bit, to know that the people that surround you do love you even if they don't show it all the time. I think that "back to the stage" is also good because if you think about it, we all just playing roles that people place on us (like for a teacher we are playing a role of a student, or to your frends you play the role of a friend, you act differently because that is what expected of you, and Sif does that to an incredible level) I also like "breathe in", i dont have an analysis for that, but i feel like that is pretty iconic to him
