Rider
Rider rolled her eyes at Faust's pathetic efforts at insulting her competence. Judging by how long he had taken, it seemed unlikely that Faust had had to deal with any significant threat to save Vanguard, and it was hardly like picking up a disembodied head and flying away with it was a task that required much competence.
However, before she could give any sort of reply, Faust suddenly stopped mid-speech, before informing Shirou, who had asked him questions about his connection to Sakura, that he had another “errand” to take care of, placing Vanguard's head down on the table and turning to leave.
What the hell? she thought.
“What is it this time? Another highly dangerous rescue mission?” she asked, mockingly.
Then, Vanguard spoke, rambling on in rather odd language about how this was obviously Shirou, and his arrival was a cause for celebration.
Well, I certainly can't disagree with that, she thought.
“Sakura's sister is here too. Hopefully, Sakura will be a lot happier now she has her family”, she said.
