We finally got our first trailer for Marvel Studio’s upcoming series She-Hulk. The new trailer reveled a lot of new series details and casters but it also gave us an update on Bruce Banner AKA The Hulk. When did the Hulks arm heal? If you noticed Bruce Banner’s arm is fully healed for his injuries in Avengers Endgame. So whats going on? Did it naturally heal? Is this another part of the timeline for Hulk? OR did Bruce Banner pull some gamma science healing trick?
