Reactions THOR: Thor wont know what to do at first. He was there, obviously, for moral support. He doesn't know how to do anything with the portals, or science, so during the immediate aftermath, THor will feel particularly powerless. However, having been around Darcy and Jane and Erik during important work he will know that his role will basically be to make sure the science team is eating and sleeping.
JAMES: James wont know until his dad tells him to come to the lab. He'll be upset, but also doesn't have any practical knowledge to help. He'll go to the gym until he tires himself out. Then he will make sure he goes to check on Pepper, Morgan and Torunn.
SHURI: Shuri was there with Cisco and Darcy testing anchors and has been helping with stuff leading up to the tests. She was actually fairly confident that this would work and is dissappointed that it didn't. She'll be doing math and helping the other science types.
