Rat/Aquarius and Dragon/Scorpio meet at 80-85%, a cross pairing of the hypersensitive fence-sitter and the superstar in embryo. Improbable on paper, potent in practice: one badly needs a decision made, and the other has never not made one.
Dragon/Scorpio loves at full throttle, magnetic, driven, more than a little possessive, and neurotic, dreamy Rat/Aquarius, almost congenitally unable to announce its own emotions, is quietly grateful to be claimed so unambiguously. The Rat/Aquarius's creative genius fascinates the Dragon; the Dragon's certainty steadies the Rat. It should not work, and it mostly does.
Rat/Aquarius struggles to communicate its true feelings, drifting in contradiction; Dragon/Scorpio states exactly what it wants and expects compliance. Oddly, that bluntness helps, though the Dragon must learn that silence from the Rat means confusion, not defiance.
Friction lives in fealty. Dragon/Scorpio's terminal jealousy demands oaths the wavering Rat/Aquarius is too tangled to perform on cue, and the Dragon's crash-and-burn intensity can flatten a hypersensitive partner who bruises at raised voices.
Dragon/Scorpio learns to pull in the reins on its jealousy before it wipes out another perfect relationship, and Rat/Aquarius, anchored by all that decisive heat, finally gets off the fence about something, namely this. Contradiction meets conviction; both improve.
At 80-85%, Rat/Aquarius and Dragon/Scorpio are strongly compatible. The dreamer and the dynamo; it thrives when the reins stay loose and the feelings get said aloud.
