Bob sighed as he tossed and turned in his egg. Merlin's decision to separate him from his contract master was making him anxious. The child of Endow first felt the tug of something dangerous pulling at his connection with Zero and immediately decided to reach through the bond to contact his master. Even if it was up against an ancient being way more powerful than he currently was, Bob was no coward. He would fight scale and claw to protect his kind master.
Imagine his horror when he couldn't reach his master. The mental connection was still there but in Zero's mindscape, there was only endless darkness that awaited him. For days he tried to reach Zero but there was no response, only that never-ending stretch of void. He'd almost given up hope too until Mii contacted him. Apparently, his master had fallen unconscious due to magic overuse. That explained everything.
