Description of ''The Twin'' (Mid-Credits Scene):

In the Mid-Credits Scene of the film, we see a young man wearing a fedora and jacket walking past the fallen debris of the building where the final battle took place. The man briefly sees the dead body of a man around his age dressed like a clown in the fallen debris, and walks up to the corpse to inspect it, when the clown gets up and smashes a glass vial of multicolored liquid in the other man's face, before running away from the scene. The man in the fedora begins cracking up, while blood pours down from the glass shards lodged into his face, collapsing to the ground and laughing so loud it echoes across the surrounding area.
