Well done! I see we need to add empath to that list of skills of yours.
Putting yourself in his shoes, acknowledging him, was a very good thing. And yes, sometimes just talking to them works wonders. What your describe as bright and crisp is often a sign that entities have left the building. I'll also mention that by saying the St. Michael's prayer, perhaps an angel was sent to guide him off as well.
Sometimes it takes a combo of things, and I'm very pleased this has worked for you.
One thing to mention here.....sometimes, when new skills come forth, we can act as a "beacon" to lost souls out there. If anything else pops by, use the same approach you have just used. Living near the sea often brings paranormal events front and center, including new abilities.
