Where Tyson’s opinion of coral is largely lukewarm, Jethro is fascinated by it.
Between Tyson’s army deployments and when Rosie & Jethro were engaged, they all went on holiday together and went diving. Or rather, Jethro went diving, Tyson was strong-armed into following him, and Rosie stayed up on the boat to sunbathe.
Until that boat trip out, Tyson had forgotten quite how much Jethro enjoyed coral. Or perhaps a better way of putting it would be that Tyson had suppressed the memory of how much Jethro knew about coral.
The expected whining of his anxiety about being his oxygen tank exploding every few minutes aside, Tyson actually found diving to be rather peaceful. He always enjoys water, and especially when he gets the enjoy the experience with his older brother.
It was a good holiday all around, actually. They got a little tipsy, found the time for a BBQ, lost and subsequently found a pair of Rosie’s shoes, managed to break a rented bike, and Rosie & Tyson learned more about coral than they ever really wanted to.
