I'll honestly be surprised if there aren't some cut scenes of NAT maybe calling Clint, or maybe that'll be in part 2. And Clint and Scott are totally both cast in the moulds of "one more big job and I'm out," so I was headcanoning the deal as "retired, unless it's an emergency."

I also hope that Clint's family being smoked is not why he goes Ronin, because while I OTP Clintasha, I got kind of overinvested in Laura/Nat. //facepalm Nat calls Clint, and he and Laura streak in to help because they are BOTH EX-AGENTS! ....no, probably not. sigh.
