My Scorp intuits everything about everyone everywhere. But, when it comes to someone he is in love with, his wires get scrambled and his radar is off. His insecurity makes him wonder if I'm being unfaithful, and he thinks he's picking up on things that actually aren't happening (I am completely faithful and always have been). Because of his razor sharp intuition and observation skills, he thinks these things are true when they aren't, simply because he has always been right about other people. Has to interrogate constantly because being so emotionally close to me has thrown him off and confused him. His intuition and his insecurity are all mixed up. Maybe that's why other Scorps become interrogators.

Also, I think maybe there is something in a Gemini personality that causes Scorps to think we are not the most reliable characters when it comes to faithfulness. It's just an attitude that they can sense. I personally have really open ideas about sexuality and don't necessarily think that multiple relationships at once are a bad thing. In THEORY. I would never hurt my partner by cheating. I think the open attitude is what he picks up on, though, and what keeps him nervous.
