Complete story — includes the ending
Meanwhile, the Thing is in the area at the local deli having lunch and expressing his concerns to the owner about what sort of trouble the Yancy Street Gang could be getting themselves into. He learns that there is a scheduled protest during the prisoner transfer and the Thing realises there could be dangerous trouble and rushes out to stop the gang. At that very moment, Spider-Man's spider-sense goes off and he warns the other pro-registration heroes that there is trouble coming from below them. The wall-crawler is correct, as Captain America and his forces are making their way to the location.
Blocked by protesters, the prison transport is forced to take an alternate route down Yancy Street. The moment they do, the members of the Yancy Street Gang begin pelting the heroes with bricks and other projectiles. Realising that Spider-Man is somehow detecting his influence, the Puppet Master is ordered to command one of the SHIELD agents in a helicopter to fire his missiles. Suddenly, the soldiers start attacking Iron Man and his forces. Spotting the Thing, Iron Man calls out to him and asks for his help. It's at that moment that Captain America and his forces launch their attack as well, with Luke Cage asking Ben to join their side.
It's at this moment that the Puppet Master takes control of Mouse and orders him to set a bomb. When Cee spots this, he tackles his friend sending the bomb landing on the ground. When the battling heroes notice the bomb, the Thing quickly uses one of the now empty prisoner transports to try and contain the blast. While mostly everyone is safe, Cee is struck by some shrapnel and killed. With the heroes about to renew their battle, the Thing gets between them and shows them Cee's dead body. He tells them that this is the result of their senseless conflict, the death of innocent people. When both Iron Man and Captain America plead to the Thing to join their respective sides, Ben flat out refuses and tells them that he is leaving the country until the civil war is over.
