The Second Seal
Grayson appears to be concerned about the well-being of his diving partner in the video. He became extremely agitated as the seal bit the palm of his hand. Fortunately, it does not appear that the bites are life-threatening. The diver appeared to be having a good time as he observed the seal frolic on the surface of the ocean.
Let Them Be
A command to the seal was then issued by Grayson. Grayson realized it was his turn to be noticed by the second seal, so he scurried over and began sniffing the soles of his feet. Following his observation of the other seal being handled with care, he may have become more trusting or sought attention.
