Emma shrieks and clings to Phil. Just an illusion, just an illusion, it's just- special effects- something... she repeats to herself. No special effects on Earth can pull off turning someone into a six foot tall merman in front of her, but she's pretending or she will lose her mind.

Her brain is babbling angry things about why Phil is in a coma what if he doesn't come out how could you think that was a good idea, but there's nothing to do now. So she clings and watches his face. He is, at the very least, gaining his color back.
