Attribution Theory

When considering Siffrin's trials throughout the game and he navigates each new loop, the audience gains a better understanding of Siffrin's internal thoughts. More specifically, we see how Siffrin process and tries to compartmentalize their emotions and how their mind slowly cracks from the stress of the situation, as they slowly disconnect from the reality they are trapped in. One of the most common attributions Siffrin makes about himself is that he's not good enough; that he's a failure. He berates himself for his first death which triggered the time loop, and continues to do so with every mistake they make in the loops, whether it's forgetting something and having to start over a loop or making a mistake that they could never have anticipated, time loops or no time loops. 

Siffrin believes he truly has nothing worthwhile about themself to maintain their new family unit and that something internal is wrong with them. Whatever that something is, they can't change about themself even with the loops. It's a stable part of them, in his mind. And while Siffrin can control and change so much in each loop, what's "wrong" with him can't be a fully controlled factor; eventually he'll "pull a Siffrin" and mess up again. In other words, it's uncontrollable. Given these considerations, Siffrin's attribution patterns are Internal/Stable/Uncontrollable. This causes Siffrin to slowly lose more and more of themself, forgetting their friends names, and slowly growing colder and more distant to the people he wanted to protect in the first place.
