I actually don't think the character Ryan is too old.He has always been "younger" than the actor(Jon) that portrays him. I think the character of the trace tech will be older than the actresses age of 20,she would have to be to have experience and to have gone to school.Perhaps nothing will come of the"close relationship","good first impression",etc.but I find it more unrealistic for Ryan to have no one ever interested in him,and he in no one as well. Being that the trace tech is only possibly a recurring character,why not have some interest shown,it would most definitely be backburner and wouldn't hurt a thing.It is speculation and it is the character of Ryan,so even though TPTB and writers have given him a little extra this season,I would be shocked(and thrilled) if a little love was thrown his way.
