One thing I don't get is what the Spirit told Robbie in issue's #3 preview. Robbie asked about their 'Eternal' Relationship. Eli stated that's the case but if Robbie dies, then its the its over. I don't get that. The ghost merged with Robbie because he was killed. Wouldn't Eli's Spirit simply protect Robbie if he was in a fatal situation in order to protect the host?
