[ He opens his mouth to deny it, immediately and categorically, but stops himself before he even makes a sound. Rey deserves the truth. Not just part of it. So he takes a beat, looking down at his drink, wanting to be honest and not to hurt her. It's a fine tightrope to walk. ]

....I'm not gonna lie to you. I'm a little afraid something might happen someday to make you consider the Dark Side again.

[ Cisco looks up at Rey, apologetic, face grave. He gnaws at his lower lip a moment before he explains: ]

Not 'cause of Ren. And not 'cause I think you're evil on the inside or weak or- whatever bad things you might be thinking. The only reason I worry about that is because I trust you. A lot. Which I know sounds like a contradiction, but. Trusting people... caring about them... letting them get close to me... makes me afraid of them, a little. It's not just you. It's everybody.

[ He looks back to the glass in his hands, tapping at it, swirling the liquid inside it. It wasn't easy, admitting just how broken he was. How he had just come to accept being afraid of people as an unavoidable side effect of any degree of intimacy and trust. Cisco knows it's messed up, but there was no changing it as far as he could see. Eobard had done quite the number on him. ]

But the thing I'm much more afraid of is that you'll get hurt. That he'll snap and attack you, or you'll get your hopes up and he'll disappoint you again.
