Sal is the kind of person who wouldn't be very helpful in group plottingness. His thing is more or less: I give you the information, you do with it what you will. Plus, his main focus at this time is on Asgard in a very narrow-minded fashion.
But Tailypo is a good assistant character if you need one! If Reno can persuade a worthwhile trade with Tailypo, he would help.
