Okay, I may not have been clear enough with my suggestions. I will try to rephrase to make it clearer:
Rey could indeed be a current member who, as a result of out last encounter or sojourn, has been delayed in town for one of the following reasons , and is just now catching up to us.:
1. ... He might have been conducting personal business in town, "smoothing" someone we upset, or even setting up our next job .... He would have known where to go to meet us as soon as his business was finished.
2. ... He might have been in town, delayed because he was recovering from an illness (mild poison? hangover?, etc.?) contracted during our last job or foray. Once recovered or well, he would have intended to meet us later, again knowing approximately where we would be ... .
"What business? What illness?", you ask? Ummm ... not a clue. Up to DM and player, there, too.
