Does Rin-chan, my magician goddess, holds a crush for Shiro?

Spoiler:

1. In episode three she was aggravated when she discovered Shirou's body, long after Lancer stabbed him through the heart. Then, she proceeded to heal him back to life, although she was supposed to only pay respect or feel sorry for the witness' death unawared that was Shirou at that time.
Archer made him remark about that fact: Using her magic to heal Shirou, although she shouldn't had used it if was another person instead.

2. In episode four she called for Shirou's body, second time he apparently dies, that she has not enough magic to save him this time, and her mood showed angsty and shocking.
