We all know that supporting characters are put through the ringer in comic books. When their fathers are not being crushed by debris or blown up during intergalatic wars, they're being thrown off bridges or buildings and stuffed into kitchen appliances. It's rough, and becoming a little banal. It's time someone shook things up.
In Daredevil, Mister Fear wants to make sure Daredevil is too busy to stop Fear from taking Kingpin's place in the underworld. He douses Gladiator with his fear gas, making him kill at random with no memory of his episodes. While Daredevil is trying to find out the source of Gladiator's madness, he doesn't notice that Milla is becoming more and more paranoid.
While Daredevil is confronting Mister Fear and the Enforcers, Milla is confronting Mafia heiress Lily Lucca, thinking Lily is trying to steal Matt away. Lily just needs help leaving the Mafia behind, but Milla becomes violent and tries to push Lily into the path of an oncoming train, but knocks a bystander down instead. While the Enforcers pound on Daredevil, Mister Fear reveals that the same gas that turned Gladiator into an unpredictable murderer was used on Milla.
Now, Matt Murdock has to save his wife from being inprisoned in a mental ward, leaving Mister Fear to consolidate his empire without Daredevil intervention. Of course, Daredevil is hellbent on finding Fear to get an antidote to his fear agent, but I think it's an ingenious twist on the paramour in danger plot. By making Milla a danger to others, Mister Fear has Daredevil consumed in both his public and secret personas.
Brubaker is a crafty storyteller and is making Daredevil one of the best books being published.
