This gives Hobgoblin enough time to escape with his son, Jay. Coldheart rushes at Spider-Man, but Spidey easily evades her swords, and kicks her in the face, letting him catch up with the Hobgoblin. She fights Hobgoblin on the roof of the building, but the Hobgoblin, realizing he's losing, throws a pumpkin bomb on the roof, sending his son flying.
