Shirou and Sakura
Shirou frowned at Irisviel's dismissive reply. Seeing his annoyance, and herself also annoyed by the abrupt way Irisviel dismissed Shirou, Sakura spoke up.
"It does concern us", she said, obviously annoyed by her dismissiveness. "What is going on?"
Still, despite the annoyance they felt, they didn't ignore her command. She was obviously trying to save them from something, and there was no-one else here for them to save. Aside maybe from Togan, but Sakura was sure he could fend for himself.
In fact, he's probably the one who caused the gunshot, knowing him..., she thought, ruefully.
