Rider
To Rider's distress, Sakura gave her no response, instead simply standing completely still, gripping the cutlery in her hands. Rider could sense a servant breaking through the bounded field, but she made no effort to intercept it. Right now, dealing with Sakura was more important, and Vanguard could handle the servant if it had bad intentions. Instead, she pondered how to react, watching whilst Sakura's beloved dragged a chair over and sat in it, before pulling her down as well.
Rider watched on with great distress as Shirou pulled the kicking and fighting Sakura into his arms, overwhelming her with his strength and trying to comfort her. But, Rider knew something was badly wrong. Sakura was obviously having a panic attack, obviously did not know where she was, and she was sure that Shirou was not helping.
"What's happening to her? Can she hear you?" Shirou said, addressing her.
Rider knew she had to respond but, first, she wanted to get through to Sakura, if she could.
Sakura! Sakura! It's OK, I'm here, it's just me and Shirou here, she said, trying to reach her master.
Then, she addressed Shirou.
"Shirou, stop, she's obviously distressed. I know you're trying to help, but she's hallucinating, something about a dog trying to eat her, you're making it worse by holding her down", she said.
