Scorpio belongs to the element of Water and moves through life in the Fixed mode, ruled by Pluto. Pisces belongs to the element of Water and moves in the Mutable mode, ruled by Neptune.
Two water signs feel each other before a word is spoken. The emotional understanding runs deep and the intimacy builds quickly. The watchful point is that two deep feelers can mirror each other's moods and lose sight of solid ground.
The fixed partner holds the frame; the mutable partner fills it with colour. A balanced rhythm — but the fixed partner should try not to read the mutable partner's flexibility as indifference.
Both signs belong to the receptive, inward polarity, so your connection thrives on intimacy, atmosphere and quiet routines. Push yourselves to step out of the cocoon now and then.
