Rider
Rider continued to hold Sakura, watching as she complained loudly at Shirou's attempts to remove her from him, only holding on to him even more tightly. Rin came over and attempted to persuade her to let go, but she was clearly not listening.
Clearly irritated that Sakura simply would not let go of him, Shirou removed his coat and, then, pushed Sakura's arms up and off his body. Rider held on to her, preventing her dropping, as he took hold of her legs and pulled them away, freeing himself and leaving Sakura grasping onto his coat. Rider laid her master down over her arms, one arm supporting her back and the other supporting her knees as the Shirou she had been holding walked to the edge of the building and jumped off, not even attempting to regain possession of the coat from the sleeping girl.
Then, the Shirou approached the sleeping Sakura.
"So, shall we head home now, Tohsaka and I still need to see the place", he said, causing Rider to give him a perplexed look, as if to say 'she's asleep, idiot, she's not going to hear you'.
OK, well, I guess we'll need to go back now, she thought. Taking all three of them will be difficult, though.
She turned to Faust to discuss how best to get back but, before she could say anything, he addressed her.
“Excuse me, but I need to attend to something right now. Rider, make sure you get Rin, Sakura and Shirou home safely. If I’m not back before you leave, I’ll meet you at the house", he said, the emphasis on his words , before leaping onto a giant black crow that he had created.
Rider glared at him, annoyed at the way he had treated her as if she was too incompetent to manage such a simple task.
"I'm not an idiot", she said in response as he flew away.
Still, she wasn't entirely sure what the best method was. It would be difficult to safely transport four people on Pegasus, but Sakura was tired and needed to sleep, and Rin was obviously cold and needed warmth.
"Rin, Shirou, do you two think you can keep hold of me if we travel on Pegasus? I will carry Sakura", she said.
She probably could get them all on, but she needed to be sure the two of them could keep hold of her, since she could not do much whilst she was holding the sleeping Sakura.
