His Dean

Meanwhile, at that moment, in a private plane that was heading towards Country M, Randall stared at Kyle's image through the laptop.

When Ruben had contacted him about the possibility of Dean being found, he had been ecstatic. He couldn't believe his longshot had actually worked. Since Dean was the type to travel around (sowing his seeds, so to speak), Randall had sent his images to all of his contacts in the world. 

He didn't care if it was a slim chance, he took it. After all, Dean may very well enter another club just like he had entered his.

Randall may have not been able to get any clear images of Dean, but Randall had one talent. He could draw. 

He could draw very, very well.

Thus, Randall had drawn a very realistic black-and-white sketch of Dean and distributed that. Sure enough, he got lucky. Ruben had sent him a screenshot of Dean that as he was waiting at the entrance of is club. Immediately, Randall knew it was him.
