This freedom loving sign will surly bring out the worst in Scorpios nature.
Mutual distrust is easy here.
The Scorpion possessiveness will make life unbearable for Sagittarius. It is true that from the sexual standpoint, Scorpio is attractive to the Sagittarian lust, but thats where the compatibility ends. Not a recommended combination. Live and learn is about the best thing to expect here. Both can bring out some of the other's better qualities but the chance of anything long lasting is remote.
