Ian was amused by Zane's question. Although his friend had not implicitly said it, it was evident from the man's tone that he was worried Mina would wake up, and Ian would somehow take advantage of the situation. Half of Ian was annoyed, but another half was surprised that Zane knew him well enough to guess what he wanted to do.
Ian was not an angel, and if Mina woke up while he was placing an ice pack on her face, he planned to ask her all the questions he had been holding back. He wanted to know what she was hiding from him, and what she had lied to him about, but most importantly, he wanted to know how she felt about Cylus. Before the nurse could respond to Zane's question, Ian dismissed her.
"You can go." The nurse bowed her head and scurried out of the room. "And you can wipe that look off your face,' Ian said addressing Zane.
"What look?" Zane shot back, but he knew the look Ian meant. It was a look he had been giving his friend often since Mina's arrival.
