A full reading for Rooster × Sagittarius meeting Rat × Scorpio is on the way. In the meantime, the score above is computed from the canonical element matrix and sign-cycle distance, and the profiles below cover each side individually.
You cannot tell a lie, or at least, you cannot tell a lie that sounds like a lie, although you wish you could. The honesty of the Rooster/Sagittarius, though greatly valued by others (especially your adversaries), is the bane of your existence. Luckily, you are a bundle of incurable typical Sagittarian optimism, so this doesn't bother you as much as it would a different DoubleSign. Try to figure out the mannered anodyne of the "white lie" -- it'll spare your relationships many an unintentional headache.
Manipulation, anyone? The Scorpio side of you is always out for number one, and the amazing quality of your self-aggrandizing tactics is that you so often get away with it by means of your Rat-induced radiant personal magnetism. Direct and forthright, you manage to defuse animosity by making no secret of what's in the deal and for whom. Others can respect such a straight-talking competitor; even if the Rat/Scorpio's concomitant razor-sharp wit and acid tongue can sometimes keep potential allies at bay unless kept in careful check.
