I reckon Deo'iel don't really come with notable opportunities of social, economic or political power, and I doubt Yanin's father would ask for their help. So either Marcus or someone mentioned him at a social gathering (Yanin might be not the most charismatic individual, but his memory is nearly as good as mine) of some description or he encountered something about him during his and Jordan's time as guards. Let's give it 20% probability. *consults RNG* 4... Huh. I guess that makes it a yes? 

	Might even collab something with it if it [i]was[/i] his guard time...
