When Shirou tries to pull the I Work Alone card on Yosuke, the other teen flat-out refuses to walk away: Shirou is crazy enough to apologize to someone who just tried to kill him out of envy, and as such Yosuke is going to watch his back, understood?
Chapter 25: Taiga's shadow pretty much hit every issue she had, but she doesn't reject it outright because she knows things are different with Shirou and that he respects her. This ends up stopping her from being murdered by her own shadow.
