Subaru laments that he could not do anything or save anyone, and has no options left. Exhausted, he suddenly takes off running at full speed as if he's made a decision... To save Emilia, Subaru approaches Crusch to negotiate the formation of an alliance. His terms are a bit difficult for Crusch to believe, but she can see that Subaru isn't lying.
I'm sorry it's sudden, I really am.
Lamento que sea repentino.
Lamento que sea repentino.
Sinto muito por ser tão repentino,
 mas precisamos fazer isso.
