" We rested, people and octopus regarding one another for several more minutes. And then, to my surprise, she floated up again to us. As she rose, we scanned the bottom of the barrel and saw that she had dropped the squid Wilson had fed her. We wished she had eaten, but we learned something new: Hunger was not the reason she had surfaced earlier, and it wasn't what brought her now.

The reason she surfaced was abundantly clear. She had not interacted with us, or tasted our skin, or seen us above her tank for ten full months. She was sick and weak. In less than four weeks, on a Saturday morning in May, Bill would find her, plane, thin, and still, dead at the bottom of her barrel. Yet, despite everything, we knew in that moment that Octavia had not only remembered us and recognized us; she had wanted to touch us again. "
