Preface: this is all hypothetical.
So I've got a ms out in the query trenches, a few agents have the partial, etc. Business as usual. But then I get a full request on a previous ms (an agent who had it and passed also forwarded it to her colleagues, one of which liked it). What do I tell the other agents (with the current ms) if the previous ms one wants to offer me rep? Again, nothing has happened, but if it does, ???
