Sounds very well handled to me.
As an frequent flyer with a PPL and a little experience of line SOPs in a sim (so having a basic grasp of how a big jet is operated), I wonder how many airlines train certain flight attendants to assist the remaining pilot in the event of such an incident?
I would have thought that someone from the company, familar with procedures and trained to assist, for example, with checklists would be potentially very useful, even if the remaining pilot could manage by themselves.
