This information had reached him in the form of a link copy/pasted to the tail end of the calendar invite. They hadn’t bothered to warn Amelia, so maybe it was an age-related thing. But they had hastened to assure him that oxygen tanks on wheels would be available at the helipad and he shouldn’t hesitate to just grab one on his way past.
