Kevin may not be salvageable, but I'm willing to roll the dice. The world still needs heroes -- maybe Kevin can eventually be half as good as his father.

Synopsis for "Like Father!"
At the Maria Stark Academy, Kevin Masterson is apparently at it again, fighting another student. After his mother and step-father pick him up, they try to talk to him, but he's again not listening. He walks off alone and is met by Sharon Carter, who takes him to meet Steve Rogers. Rogers informs him that he recently came into possession of an item—the Thunderstrike mace—and believed it should be given to its rightful owner. Kevin picks it up, expecting to be transformed, but nothing happens. Feeling like he's being taken advantage of, he has Sharon drop him off. As Kevin tries to figure out what to do now, the Rhino attacks an armored vehicle, causing a woman and her child to become trapped in a flaming car. While trying to use the mace as a prybar to help get the child out after another bystander has saved the mother, the car explodes. Strangely, Kevin is all right and has protected the child, but he has also seemingly transformed into his father Eric Masterson's Thunderstrike form.
