Something isn’t right.
Nan is perhaps the most knowledgeable person on swimming with whales. It’s an important aspect of her job, and something she’s done hundreds, if not thousands, of times over her career as a conservator and marine biologist.
So she realized she was in trouble when she was perplexed by the whale’s conduct.
The closer the whale got, the more obvious it became that something wasn’t right.
Whales generally swim by humans, oblivious to their presence. But this one had his attention fixed on her and was heading towards her in a straight line.
He didn’t stop even after slamming into her and pinning her on his head.
