A few days after Joan woke up for the first time, her son Joshua also started looking healthy enough to wake up. After his body got used to the taste of the void meat and started accepting more of it, Joshua started recovering extremely quickly. Although he was still skin and bones, he wasn't deathly pale anymore, and his gaunt face wasn't as hollow as it had been when the two of them were first saved from the boat.
Joan didn't want to leave Joshua's side after he started showing signs of waking up, so Toz brought food and water to them and talked with Joan when he felt like it. The cats also regularly checked in on Joan in case she felt lonely.
Eventually, Joshua recovered enough to open his eyes and squint as he looked around. Though, it was only temporary as he closed them and fell back asleep after feeling his mother caressing his head and hugging him.
