Hell on Earth - Black Bolt has been stricken with amnesia, and doesn't realize the danger in speaking. He is lost in man's world, unable to help his fellow Inhumans stand against Maximus the Mad's newfound mental powers.
Blood Will Tell - The Black Widow is in a foul mood, blaming herself for the deaths at the end of the last issue. She still works to protect the blood from the Astrologer's group, but she's so concerned about killing again that it interferes with her duty.
