SilvaSurf i typed "saul" in the rarbg site and got a link with the 6th season ... with subs
more generally if the sub is not included in the release and i can't find a release with subs i search the sites listed by [Login to see the link] (always awesome answer) and try to match it with the release name or the format x265 / webdl / 1080p or else
if that doesn't work i take whatever sub is closer in name and i use the built-in function in vlc to delay the sub or the opposite (just add shortcut and it's quick) then you go (sometimes you had to resync mid episodes coz of the ads but now i rarely take hdtv) hope it helps
And a message in the bottle for a sub i cannot find : the two seasons of AL WASEM (syrian i think) english subs
if someone has it that be awesome
