I think the reason that your v2 script doesn't work is because in the txt [sRockyT.name] and [sJulia.name] are not available at the same time, so the script wont find a match.
heren an example from npc_julia.rpy line 758:
sRocky happy "¡Buen día [sJulia.name]! ¿Preparo el desayuno?"
I've corrected the English translation so al the names are converted to variables. Now the incest patch v1 will also work in English.
juist download the zip file "fix_eng.zip" and overwrite the game folder (unpack in the main folder Area69-0.60).
It's possible that i miss something, just let me know
