(this is a timeline where agent milton and ross just wanted a visit, nothing else)

while with the van der linde gang at the camp, some people came in and there was agent milton and agent ross

Milton:"good day people... mr. Van der linde... Mr. Matthews i presume..."

Then John marston stands up from his bench at the table and then milton said

Milton:"and who are you?"

And john marston decided to give a fake name which was very obvious

Rip van winkle(john marston):"rip van winkle"

Milton nods and say

Milton:"huh... Good day, sir..."

And after agent milton and ross left, everyone went back to their thing but john marston? Oh he's gonna get teased a lot by being called "rip van winkle" now
