Well, in theory trading Currency to Ramesses for Aesthetics or something else will get us -1 with Brennus, which should be countered T131 from shared civics. That means we can trade for his Calendar on T135 (if he really finishes in 9 turns) and start doing heavy trading with Ramesses after. Or we can give Brennus some tech gift for another +1 if there is some kind of freak -2 hit trading Currency with Ramesses. Sure, I'd say go for it. If it goes badly we can make another spy in Paris next. Should always have two spies for when the open borders go down to scout and cause mayham.
