My character's soul left their body (it's magic) right after a brain injury and didn't warn anyone they were going. Their doctor isn't very familiar with magic and THINKS it's a coma. For a week, they're a 3 on the Glasgow scale except one couple-minute waking. Then the soul and body reunite. What would be a reasonable response to a formerly unresponsive patient suddenly getting up, getting work done and being mostly lucid and coherent (minor impairment from the brain injury but only minor)?
