The hour went past very quickly.
Sam just stayed inside the divine dimension. So, he spent almost ten hours in there. He had one of the live water creatures inside. He performed various tests on it.
He collected its blood samples, genetic material and put it through various tests. By now, he has done these kinds of tests way too many times and he had the apparatus ready. So, he managed to get most of the information.
One of the major revelations he has is that this creature is nothing but a genetic mutation gone wrong. The guy who performed the experiment seemed to have tried to create a mutation, which is very close to the transformation.
Just like the Lycans, Giants and the shapeshifters Sam has worked with and experimented with before.
