Somewhere out there in Thailand there's an SSI instructor who did something wonderful for my friend's daughter ... he turned her into a diver. Not just someone who swims around underwater, but someone who was taught enough to know how to think, control, adapt, and enjoy herself in that environment.

I don't doubt that the instructor did a lot to get the young lady off to a good start but a few other angles do come to mind.
1. Being in warm water she probably got to see some very competent divers in warm water. For some divers getting to witness what competency looks like is a huge head start. If you get into a region where mediocre instruction is the norm new divers have less to work with as role models.
2. I suspect she was something of a natural. She probably came to the sport with solid waterman ship and her adaptation to scuba diving was solid if not easy. The instructor could certainly be a contributing factor for a lot of this.
With decent skills and a perception of what competent diving should look like she was left with the cold water gear. I'm sure your skills in configuring her weights and the fit of her BC helped ease the migration.
I think there were probably enough kudos to pass around to all involved.
