Caenan is going to pass up his Outcast days, even if it is only temporarily. In order to explain his poofing from the site whenever life ate me I writing it as though whenever he had the sickness that characters got from the SWP he had tucked away thinking it was the end of him. During that time he had time to realize that he doesn't have any friends who would even miss him if something happened to him and it is going to lead him to try to learn how to interact in a herd. 

It could take a fun twist and if you have a character you want to write as though they had came across Caenan in his messy time and offered him company and convinced him to eat etc. Caenan could have been sick enough that he only vaguely remembers their meeting and could be surprised to meet again or the friendship could build until he eventually remembers after something familiar is said. 

Whether they are meeting again, or meeting for the first time it would be at the Endless Blue whenever they meet.
